Cinnamaldehyde: Improving Vulcanized Rubber Properties




Hua Qi (Zhangjiagang) Chemical Co., Ltd. has invented a modification of vulcanized rubber composition. It includes: rubber selected from natural rubber or synthetic rubber composition; methylene donor; and methylene acceptor substituted aralkyl phenolic resin. The aralkyl substituted phenols (resorcinol) methylene resin can be unsubstituted or substituted phenolic compounds and vinyl aromatic compounds, as well as cinnamic aldehyde in the organic metal phosphite or sub-the presence of phosphate catalyst prepared by the reaction. 
In the test of Tensile strength and dynamic mechanical properties, the two phenol phenolic resin showed much better performance than R-80 and resorcinol - formaldehyde (RF) resin products.
The modification of vulcanized rubber composition is more excellent than traditional rubber reinforcing agent, which can be widely used in pneumatic tires, hoses, rubber soles and other products.

Good Effect of Cinnamaldehyde

Cinnamaldehyde and vanillin spice traditionally used as food, there is a better anti-mildew and antibacterial activity. Vanillin as a white or light yellow crystal, owing to its unique sweet vanilla aroma, used for making ice cream, chocolate class Western-style dim sum; while Cinnamaldehyde as a unique cinnamon scent with a yellow liquid, used for bread, meat, fish, vegetables , eggs, soups, cakes, desserts, sauces and seasoning compound.

According to the research, Cinnamaldehyde and vanillin, while having a good mildew and antibacterial, but individually as a preservative, the mold can play a role in concentration, has obvious smell, thus affecting the food value of the goods, including Cinnamaldehyde odor flavor more pronounced.

In order to overcome these shortcomings, researchers with a mixture of both active ingredients as a mold made of mildew, mixed-use, their respective effective concentration when used alone is only effective concentration of the respective mold 1/10-1/20 , and the smell disappeared, food appearance of browning did not occur. Mildew in cinnamaldehyde and vanillin in the weight ratio of 0.001-1, to 0.001-0.1 most appropriate. The preservative can be made that the ratio of vanillin and Cinnamaldehyde in alcohol solution, water - alcohol solution or propylene glycol solution can also be sprayed on the above-mentioned preparations alcohol solution of glucose, dextrin or large rice in the system through the dry into a powder application.

The use of vanillin and Cinnamaldehyde mixture made of antifungal agents, is absolutely safe to humans and animals can be widely used in food mold, especially for cakes, pastries, rice cakes, rice cakes, jams and other food for mildew. To use a wide variety, such as coating, powder scatter, spray on food surfaces, or to blend in the food raw materials, or to apply on food wrappers on both.

Application of Cinnamic Aldeyde


Name: Cinnamic aldehyde
Synonyms: cinnamaldehydeβ-phenylacrolein , Trans-Cinnamaldehyde
Molecular formula: C9H8O
CAS: 104-55-2
Appearance: Colorless or light yellow liquid
Aroma Unique fragrances
Content (Weather chromatography analysis) 98%
 
As the constant development of scientific and technological level, the scope of application of cinnamaldehyde become more and more widely, applications continue to extend, in the flavors and fragrances, food additives, pharmaceutical chemicals and feed applications, and other aspects. This article focuses on cinnamic aldehyde in the pharmaceutical and chemical fields.

1. Cinnamaldehyde-- the Application in Medicine

1. Disinfection Antiseptic, especially for Fungi a significant effect.

Escherichia coli, Bacillus subtilis and Staphylococcus aureus bacteria, Staphylococcus albus, Shigella, typhoid and paratyphoid A bacillus, pneumococcus, Aerobacter aerogenes, Proteus, Bacillus anthracis, Salmonella enteritidis, Vibrio cholerae, etc. are inhibition. And against Gram-positive bacteria, a significant bactericidal effect can be used to treat a variety of diseases caused by bacterial infection. Minimum inhibitory concentration (MIC) for the 0.02-0.07ul/ml, right deep pathogenic fungi, MIC for 0.1-0.3ul/ml.

Japanese medical experts recently found cinnamaldehyde a significant effect on the fungi of 22 species of pathogenic fungi conditions Cinnamaldehyde studies have shown that anti-fungal effect: Cinnamic aldehyde is the active anti-fungal substances, mainly through the destruction of fungal cell walls, so that drug infiltration of fungal cells, destruction of organelles and play a bactericidal effect.

2. Antiulcer, strengthening the stomach, intestinal movement.

3. Fat Decomposition.

Cinnamic aldehyde can inhibit the epinephrine and ACTH right of free fatty acids to promote the synthesis of glucose and fat, cinnamic acid, also have such effect, but the role is far greater than cinnamaldehyde cinnamic acid. Thus, drugs can be used for blood glucose control, enhance the performance of glucose-insulin replacement, diabetes control.

4. Antiviral Activity of influenza virus, SV10 virus, a strong inhibitory effect caused by the tumor.

5. Anticancer effect. Inhibit tumors, and have the anti-mutagenic and anti-radiation effect.

6. Expansion of the role of blood vessels and blood pressure. Right adrenal hypertension have blood pressure lowering.

7. Aphrodisiac effect. Treatment Research Center, Chicago, a study showed that cinnamic aldehyde makes a certain effect aphrodisiac for men.

8. Commonly used in external medicine.

Applied in massage fluid, beauty products, promote blood circulation, which can improve water retention, scars on the skin, softening and remove fibroids.

In short, cinnamic aldehyde can be used not only to its own raw material medicine, but also to a variety of external agents, finished drugs, the process can be further in-depth synthesis of a number of powerful drug efficacy.

II. Cinnamaldehyde in the application of chemical

1. Organic chemical synthesis. For the synthesis of α-bromo cinnamic aldehyde, cinnamic acid, cinnamic alcohol, cinnamic nitrile and other products.

2. In the industry, can also be made of color reagent, laboratory reagent.

3. Insecticide, insect repellent, refrigerator deodorant, preservation agent.

Larvae of the Aedes mosquitoes spread yellow fever has a strong killing effect, it will become a new type of insecticide. Cinnamaldehyde is safe, environmentally and smell fragrant, which can be used directly drains (sewers) or vehicle-specific flavor, air fresheners, oxygen generator, refrigerator deodorant, preservation agent.

4. Cinnamic aldehyde can also be applied to oil exploration in the sterilization algicide, acidification inhibitor, to replace the current use of glutaraldehyde and other traditional antiseptic bactericide, which can significantly increase oil production and improve oil quality and reduce mining costs. At present, Hebei Oilfield, Shengli Oilfield have purchased Cinnamaldehyde from us. 

5. Cinnamaldehyde is widely used in anti-corrosion anti-mildew freshness.

6. Cinnamic aldehyde gum sterilization deodorant.
Liangbu Wu reported that the U.S. University of Illinois at Chicago College of Dentistry has an expert report the latest research results, contain cinnamaldehyde composition of natural plant extracts such as the taste of chewing gum can kill bacteria in the mouth , and thus reduce the production of bad breath.

III. The flavors and fragrances 

Modulation as cinnamic aldehyde not only can flavor a variety of flavors, but also on oral play the dual effect sterilization and deodorization. Commonly used in toothpaste, chewing gum, breath fresh oral care agent.

IV. Cinnamaldehyde application in the food industry

Cinnamic aldehyde in foods commonly used in the consumption of spices, fresh anti-corrosion mildew (paper), and a very good seasoning (material) oil, used to improve the taste flavor. Such as: instant noodles, chewing gum, betel nuts and other foodstuffs, as well as bread, cakes, pastries and other baked goods.

Cinnamic aldehyde can be used for anti-mold plastic wrap. Fruit, food preservation and packaging materials.
