cinnamyl chloride
cinnamyl chloride
Alias: 3-phenyl-2-propylene cinnamyi chloride
CAS Numbers: 102-92-1
Packaging: 25 kg cardboard barrels
Specifications: 98% pharmaceutical grade
Chemical properties: white or light yellow needle crystal. 37-38 ℃ melting point, boiling point 257.5 ℃ and 131 ℃ (1.47 kPa), the relative density of 1.167
(45/4 ℃), the refractive indexes, 1.614 (42.5 ℃). Soluble in petroleum ether, carbon tetrachloride and hot ethanol, insoluble in water. Slow decomposition in the water.
Production method: the cinnamon sodium and second 2 cinnamyi chloride reaction. Will b two cinnamyi chloride and benzene match into solution, stir in the next will dried cinnamic acid sodium points
Time to join, every time to join to emit carbon dioxide reaction added again next time. Then reflux 2 h. After a little cold, will produce of sodium chloride and trace not of the reaction of cinnamon
Sodium filter. First in atmospheric pressure steam filtrate except benzene, to collect 131 ℃ vacuum distillation (1.47 kPa) fractions, for a quick products, production rate of 75-90%. Need to purification
To use carbon tetrachloride heavy crystallization. Cinnamic acid and methylene chloride and reaction from cinnamyi chloride were cinnamon
Main application: this product can be used for synthetic organic intermediates, made by the amidation cinnamon amide; And Hai benzene function may be the N-cinnamon usions-N-(phenyl amine, cinnamon cinnamyi chloride
In the medicine synthesis can also be used to synthetic antiphlogistic analgesics XinNuo yesterday kang (Cinnoxicam) can also be used for the synthesis of other fine chemicals, etc. For the determination of trace water
Points of the reagents.
