The combination of acrylic acid and benzoyl chloride to give acryloyl
chlorid in good yield when the carried out by using pure or distilled
Reagent should be used. Before mixing these two reagents you must add
pinch of hydroquinone(to avoid polymerisation) then maintain a temp of
110-130 c. During temp
increase (i.e at threshold temp reaction starts vigourously.You should
maintain chilled & cooled circulation due to because it is an low boiling
nature of acrylchloride. At the receiver flask also you should add a pinch
of hydroquinone. The distillation of acrylic acid andbenzoyl chloride
by distillation set up with temp maintanance and chilled water
circulation.

Yours
