Alkanepolyols

Alkanepolyols. Kaplan, Leonard (Union Carbide Corp., USA). Ger. Offen. DE 2643897 31 Mar 1977, 42 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07C031-18. PRIORITY: US 75-618023 30 Sep 1975. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 23 The title compds. are prepd. by catalytic hydrogenation of CO at 100-375.degree./56-3515 atm in the presence of Rh carbonyl catalysts and amts. of N compd. Lewis base promoters such that the optimum yield of polyol is exceeded by <50%. Thus, heating 1:1 CO-H in 75 mL sulfolane contg. 0.77 g rhodium dicarbonyl acetylacetonate [14874-82-9] and 7.0 mmol N,N,N',N'-tetramethyl-1,8-naphthalenediamine [20734-58-1] 4 h at 240.degree./534-590 atm gives 4.4 g MeOH [67-56-1], 4.8 g HOCH2CH2OH [107-21-1], and Rh catalyst recovery 90%; compared with 2.4, 0.8, and 39, resp., in the presence of 0.20 mmol diamine.

Polyhydric alcohols and their ethers and esters and oligomers. Kaplan, Leonard (Union Carbide Corp., USA). Ger. Offen. DE 2643193 31 Mar 1977, 36 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07C031-18. PRIORITY: US 75-618061 30 Sep 1975. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 23 The title compds. are prepd. by hydrogenation of CO at 100-375.degree./56-3515 atm in the presence of Rh carbonyl catalysts and N compd. Lewis base promoters in amts. proportional to their basicity. Thus, heating 1:1 CO-H with 75 mL sulfolane contg. 3 mmol rhodium dicarbonyl acetylacetonate [14874-82-9] and 1.25 mmol sparteine (I) [90-39-1] 4 h at 240.degree./562 atm gives 3.9 g MeOH [67-56-1], 4.8 g HOCH2CH2OH [107-21-1], and Rh recovery 88%; compared with 2.9, 0.3, and 71, resp., with 0.31 mmol I, and 0.9, 0.6, and 100, resp., with 5.0 mmol I.
