- Product Name:Propyl gallate
- CAS Number:121-79-9
- Molecular formula:C10H12O5
- Molecular Weight:212.2
Yield:121-79-9 98%
Reaction Conditions:
with brominated modified sulfonic acid resin at 100; for 5 h;
Steps:
7
100 g of gallic acid and 200 g of n-propanol were weighed into a reactor,20 g of the brominated modified sulfonic acid resin obtained in Reference Example 2 was added,Electric stirring,Heating to 100 DEG C to react for 5 h, filtering to obtain the filtrate, and recovering brominated modified sulfonic acid resin;the filtrate obtained in step (1) is distilled off excess alcohol to obtain the crude product, then recrystallization, dewatering and drying are carried out by deionized water to obtain n-propyl gallate,The yield was 98% and the product purity was 99.9%.
