Abstract
Orthoformic acid esters are prepared by reacting hydrocyanic acid with a monohydric alcohol in the presence of an inert anhydrous solvent and an excess of hydrogen chloride, and reacting the resulting formimido ether hydrochloride at below 100 DEG C. (preferably at 40-45 DEG C.) with an excess of the alcohol, there being added to the reaction mixture after the formation of the formimido ether hydrochloride, either before or after the addition of the excess alcohol, a compound <FORM:0853405/IV(b)/1> wherein R1, R2 and R3, which may be the same or different, are hydrogen atoms or C1-5 alkyl radicals, to a pH of 1-3 when measured in aqueous solution (e.g. with a moist indicator paper). Preferably the temperature of the reaction mixture is maintained at between-20 DEG C. and + 10 DEG C. during the addition of the base. Specified alcohols are methanol and ethanol. Specification 637,757 is referred to.
