Phenylacetyl chloride

Chemical properties of this product is colorless or light yellow liquid, b.p. 94 ~ 95 ℃ / 1.6 kPa, n20D 1.5325, relative density 1.169, soluble in ether, benzene and other organic solvent, water decomposition.
The use of phenylacetyl chloride is an intermediates for the fungicide phenylein and the rodent.
USES for the preparation of spices and organic synthesis
USES for medicinal, pesticide and spices intermediates
USES this product as the spice and its organic synthesis intermediates.
Use organic synthesis.
Acylating agent.
Methods of production are made by the reaction of phenylacetic acid and chlorinated sulfone.
By mixing the hydrochloric acid sulfane, which is waiting for mole, the reaction is to release sulfur dioxide and hydrogen chloride gas at room temperature.
No longer have a large number of gas emission, the reaction mixture heat to 30 to 40 ℃, 25 h insulation, add a quarter of the benzene mixture volume.
Low-temperature distillation to remove volatile matter, is gradually reduced pressure to 0.133 kPa, after being to remove all volatile material, steamed out of 55 to 57 ℃ (0.133 kPa) fractions, namely acetyl chloride.
Yield of 80-85%.
Production method of its preparation methods is in chlorinated benzene acetic acid is added to the reaction kettle and sulfoxide, heating reflux for hours, heating decompression to remove the remaining sulfoxide chloride products, vacuum distillation to finished products.
