Abstract: Continuous production of axerophthol by reaction of axerophthyl acetate with a lower alcohol using guanidine as transesterification catalyst in two stages, alkyl acetate and some of the excess alcohol being distilled off in the first stage and the remainder of the alcohol being removed in the second stage by distillation with a hydrocarbon as entrainer.

Abstract: 1,256,172. Production of 3-ketobutanol-(1). BADISCHE ANILIN- & SODA-FABRIK A.G. 6 May, 1969 [7 May, 1968], No. 23020/69. Addition to 1,191,006. Heading C2C. 3-Ketobutanol-(l) is prepared by reacting acetone with aqueous formaldehyde solution at superatmospheric pressure at a temperature above 210‹ up to 300‹ C. The reaction is preferably conducted at 220‹ to 280‹ C. at a pressure of 30-500 atmospheres in the presence of an alkaline catalyst such as a salt of an alkali metal with a carboxylic acid. Preferably 5 to 7 moles of acetone are used per mole of formaldehyde.
