Cinnamamide - 2

Physical and chemical properties: white solid, slightly soluble in hot water, soluble in ethanol and ether.


Usage


       Used as an intermediate in organic synthesis.

Spices - mainly used for the preparation of gooseberry, peach, strawberry, cherry, cocoa and chocolate aroma strong flavor.


Storage


Store in an airtight container and in a cool, dry place. Storage areas must be kept away from oxidants.


Synthesis method


By chlorinating and acylation of cinnamic acid. Cinnamamide was distilled from the crude product by reduced pressure using cinnamic acid and dichlorosulfoxide at 60-70 degrees Celsius for 3-4 hours and the crude product was obtained by vacuum distillation. The cinnamoyl chloride was slowly added to the concentrated ammonia water below 30 degrees Celsius and stirred for 1 hour at the temperature below 30 degrees Celsius 24h, pour in a large amount of distilled water, centrifugally shake dry, wash, re-crystallize with dilute ethanol to get finished product.
