ABSTRACT:
Process for producing tetrazole-1-acetic acid of maximum purity includes the steps of providing a crude reaction product containing an alkyl ester of tetrazole-1-acetic acid having from 1 to 4 carbon atoms in the alkyl group, effecting molecular distillation of this reaction product at a temperature below 130.degree.C. under a vacuum of 10.sup.-.sup.1 torr to obtain a distillant containing the alkyl ester and then gently hydrolyzing the resultant distillate to obtain the desired acid product.
