Abstract
Mono-, di-, tri- and higher pentaerythritols are formed by aldol condensation of formaldehyde with acetaldehyde in alkaline medium, in addition to the formation of other organic compounds. The conditions for the quantitative determination of monopentaerythritol in dilute aqueous solutions by gas—liquid chromatography were studied. The method of silylation in aqueous solution was compared with the use of anhydrous reaction products. The greatest effects on the precision of the determination of pentaerythritol were caused by the silylation procedure and the presence and concentration of formaldehyde. A procedure for the elimination of the effect of formaldehyde on the precision and reproducibility of the determination of pentaerythritol was developed.
