Customs Code (HS): 2916399090, rebate of 9% Tips: This product complies with GB-28348-2012 standard The main purpose
Our GB-2760-96 provides for the use of edible spices widely used in many fields of household chemicals, flavors and fragrances, fine chemicals, cigarette manufacturing, additives and organic synthesis intermediates used in the fragrance industry as a fixative agent;. Common in the deployment of carnations; oriental floral fragrance; for soap; detergent; also used for flavor and pastries cinnamate, ethyl cinnamate, can be added to cigarette tobacco, and is used as a flavoring agent and fragrance Compensation agent. cinnamate its own unique chemical properties and physical and chemical properties, it can be used as water reducing agent and other surfactant processing. Practical application
Beichen Area Comprehensive Chemical Plant researchers have successfully developed and marketed cinnamate water reducer. Preparation Process
The cinnamic acid esterification with methanol derived. The mixture cinnamic acid, methanol and sulfuric acid heated to reflux 5h, subject to an excess of methanol, cooled to sub-acid layer was washed with water and then washed with 10% sodium carbonate solution, then washed with water to neutral. crude, by recrystallization or vacuum distillation [shouji132-134 ℃ (2.0kpa) liufen], cinnamic acid methyl ester product. The yield of about 70%.
