- W2371815332 abstract "Using o-nitrotoluene as an oxidant,the improved preparation of 7-chloroquinldine was studied by classical Skraup reaction of m-chloroaniline and crotonaldehyde.7-chloroquinaldine was obtained with the yield rate of 46.7% and the purity of 99.2%.The side product was obtained and elucidated as dichloroquinaldine with the yield of 13.4%.The effect of oxidant,amount of oxidant and concentration of hydrochloric acid on the yield of 7-chloroquinaldine was also investigated.Scale-up of this procedure in the reactor of 1 000 L was carried out to yield 7 tons of 7-chloroquinaldine.The yield and quality of the product were the same as that of laboratory-scale." @default.
