Methanol production method and system. Chen, Michael J.; Rathke, Jerome W. (United States Dept. of Energy, USA). U.S. US 4476334 A 9 Oct 1984, 7 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07C029-00; B01J031-02. NCL: 568902000. APPLICATION: US 83-498437 26 May 1983. DOCUMENT TYPE: Patent CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Homogeneous catalyst precursors selective for the homologation of MeOH [67-56-1] to EtOH [64-17-5] at 200° and 300 atm in the presence of 1:3 H-CO (with formation of CO2 instead of H2O) consist of a Mn carbonyl (e.g., Mn2(CO)10) and HCO2K [590-29-4] (and optionally KI). Thus, a MeOH soln., contg. 0.075 M Mn2(CO)10 and 0.2 M HCO2K was reacted at 200° in the presence of 300 atm 1:3 H-CO. After 7 h, the soln. was 2.5 M in EtOH. A less volatile co-solvent can also be present.

Plasticizer-containing poly(vinyl butyral) sheets with reduced adhesion to glass

Plasticizer-containing poly(vinyl butyral) sheets with reduced adhesion to glass. Hermann, Hans Dieter; Fabian, Klaus; Ebigt, Joachim (Hoechst A.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3303156 A1 2 Aug 1984, 21 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08L029-14; C08L029-04; C08K003-22; C08K005-09; C08K005-17; C08J005-18; B32B017-12; B32B027-30. APPLICATION: DE 83-3303156 31 Jan 1983. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) KOH, HCO2K [590-29-4], or AcOK [127-08-2] and a betaine-like compd. are added to mixts. of a poly(vinyl butyral) having 21-28% vinyl alc. units and at least one plasticizer to optimize the adhesion to glass in the manuf. of safety glass. Thus, 71 parts poly(vinyl butyral) (contg. 22.5% vinyl alc. units) contg. HCO2K (to give alkali titer 50) and 0.07% C16H33CONH(CH2)3N+Me2CH2CO2- [92836-76-5] was mixed with 29 parts triethylene glycol ester of aliph. C6-9 carboxylic acids. The mixt. was extruded at 170° to give a film having shear strength 2.8 N/mm2 and satisfactory adhesion to glass in the manuf. of safety glass.
