- Preparation of cycloacetal compounds by catalytic reaction of erythritol with carbonyl compounds. Nakagawa, Shoji; Togashi, Hiroyasu; Hagiwara, Tosha (Kao Corp, Japan).Several substances are used for example 3453-99-4 and 186604-94-4 which are their cas registry numbers. Jpn. Kokai Tokkyo Koho JP 09020771 A2 21 Jan 1997 Heisei, 11 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: C07D317-12. ICS: C07D493-04. APPLICATION: JP 1995-192456 4 Jul 1995. DOCUMENT TYPE: Patent CA Section: 33 (Carbohydrates) Section cross-reference(s): 51 The title compds. (I and II; R1 = H, Me, C2-21 linear or branched alky; R2 = C2-21 linear or branched alkyl) are prepd. by reaction of erythritol with carbonyl compds. R1COR2 (R1, R2 = same as above) or their reactive derivs. using acidic catalysts. I and II, useful as intermediates for surface-active agents and lubricating oils, are prepd. in high yield with high purity efficiently and economically. Thus, meso-erythritol was reacted with MeCOEt in the presence of p-MeC6H4SO3H to give 90.2% I (R1 = Me, R2 = Et), which showed 3.99 mm2/s viscosity at 40°.. .
