Detailed Description

Packaging specifications: 25kg paperboard barrel
Specifications: 98% pharmaceutical grade
Chemical properties: white or light yellow needle crystal. The melting point of 37-38 deg.c, boiling point of 257.5 DEG C, 131 C (1.47kPa), the relative density of 1.167
(45/4 C), refractive index 1.614 (42.5 C). Soluble in petroleum ether, carbon tetrachloride and ethanol, insoluble in water. Slow decomposition in water.
Production method: by cinnamic acid and sodium chloride reaction and B two. The B two chloride and benzene into solution, sodium cinnamate in from time to time under agitation drying off several times to join, each added to emit carbon dioxide before adding the next reaction. Then return 2h. Slightly cold, will produce sodium chloride and trace the unreacted sodium cinnamate filter. The filtrate first under normal pressure steaming in addition to benzene, and vacuum distillation to collect 131 C (1.47kPa) fractions, namely product, yield of 75-90%. Need of purification, available carbon tetrachloride recrystallization. Cinnamic acid and two chloro sulfoxide reaction to prepare cinnamyl chloride
Main uses: This product can be used in organic synthesis intermediates, via amidation can cinnamyl amide; and phenylhydroxylamine role can be made N- cinnamoyl -N- phenyl hydroxylamine, cinnamoyl chloride in pharmaceutical synthesis can also be used for the synthesis of antipyretic analgesic cinnoxicam (Cinnoxicam) can also be used for the synthesis of other fine chemicals were reagent of trace moisture.
