104-82-5 – Reference Information

preparation

4-methylbenzyl chloride is an important pharmaceutical intermediate and an important fine chemical raw material, can be used for the preparation of p-methyl benzyl alcohol, P-methyl benzaldehyde etc. At present, the main process for industrial production of 4-methylbenzyl chloride is 3-hydroxybenzaldehyde as a raw material, and the target product is obtained by methylation of dimethyl sulfate, potassium borohydride or hydrogenation reduction, and chlorination of alum chloride or concentrated hydrochloric acid.

purpose

for the preparation of p-methylbenzyl alcohol, P-methylbenzaldehyde and so on for the preparation of p-methylbenzyl alcohol, P-tolualdehyde
