METHOD OF PENTAERYTHRITOL SYNTHESIS Russian patent published in 1996 - IPC

Abstract SU 1809593 A1

FIELD: synthesis of alkyd resins. SUBSTANCE: product: pentaerythritol, empirical formula is C5H12O4, yield is 93-96%, output is 105-140 kg/m3 p., m. p. is 258-259 C. Reagent 1: formaldehyde. Reagent 2: acetaldehyde. Reagent 3: alkaline reagent. Reaction conditions: reagent 2 is added to the circulating mixture in circulatory pump line after thermostating parental aqueous reagent 1 and reagent 3 at the total time dosing reagent 2 and reaction mass exposition for 63-42 min and at the ratio of the volume rate of reaction mass circulation and volume reagent 2 dosing (100-490):1. EFFECT: improved method of synthesis. 1 tbl, 1 dwg
