Function and application of cinnamic acid: cinnamic acid is an important organic synthetic raw material.
It is mainly used to synthesize methyl cinnamate, ethyl cinnamate and benzyl cinnamate. It is widely used in perfume industry and pharmaceutical industry. Used as an insect repellent in medicine.
Cinnamic acid is used as perfume to make cherry, apricot, honey and cinnamon flavor. It can also be used as raw material of cinnamate.
China's GB2760-1996 stipulates that China cinnamic acid is allowed to be used as edible flavor; In addition, it can also be used as raw material for photosensitive resin polyvinyl cinnamate series.
Raw materials for the synthesis of methyl ester, ethyl ester and benzyl ester.
These esters can be used as spices for cosmetics, soap, local anesthetics, hemostatic agents and raw materials for medicine (cardiotropin lactate and chlorophenylaminobutyric acid, etc.).
China cinnamic acid is also used as pesticide raw materials such as plant growth regulator and fungicide; Preservatives for fruits and vegetables.
It is used as raw material of ultraviolet agent and photosensitive resin and sunscreen for cosmetics.
