Vicinal epoxides from carbonate esters

Vicinal epoxides from carbonate esters.Some chemicals with cas registry numbers like 78241-71-1 are also used. Renga, James Michael; Emmons, Albert Henry (Dow Chemical Co., USA). Pat. Specif. (Aust.) AU 539772 B2 18 Oct 1984, 21 pp. (English). (Australia). CODEN: ALXXAP. CLASS: IC: C07C017-00; C07D301-24; C07D303-04; C07D303-08. APPLICATION: AU 81-68851 27 Mar 1981. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 23, 27 Epoxides and alkyl(ene) halides are produced by decompn. of mono- or di(haloalkyl) carbonates in the presence of quaternary ammonium or phosphonium salt catalysts (optionally as strong base anion exchangers) at 25-250°. The halogenated alkyl carbonates are prepd. from halogenated alcs.Some chemicals with cas registry numbers like 78241-71-1 are also used. and haloalkyl chloroformates. Thus, heating 4.57 g 70--20 1-chloro-2-propyl Me carbonate [78241-71-1]-2-chloro-1-propyl Me carbonate [84226-81-3] and 0.034 g Bu4PBr [3115-68-2] 2 h at 100-105° gave 2.5 g product (~100% conversion) contg. propylene oxide [75-56-9] (95% yield) and CH2Cl2. ..

Alcohol/ester fuels from synthesis gas

Alcohol/ester fuels from synthesis gas. Knifton, John F.; Grigsby, Robert A., Jr.; Herbstman, Sheldon (Texaco Chem. Co., Austin, TX 78761, USA). Catal. Convers. Synth. Gas Alcohols Chem., [Proc. Symp.], Meeting Date 1983, 81-96. Edited by: Herman, Richard G. Plenum: New York, N. Y. (English) 1984. CODEN: 51NNA6. DOCUMENT TYPE: Conference CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 67 A process for producing C1-3 alcs. and their acetate esters from synthesis gas with Ru3(CO)12-Bu4PI [3115-66-0] or Ru3(CO)12-Co(CO)8-Bu4PBr [3115-68-2] catalysts was presented. Octane response and related fuel improvement properties for gasoline mixts. contg. the alcs. and esters were discussed.
