标 题 :Process for low pressure synthesis of ethylene glycol from synthesis gas
发明人：KNIFTON JOHN F; DURANLEAU ROGER G
权利人:TEXACO INC
摘要:This invention relates to the manufacture of ethylene glcyol and more particularly to a low pressure process for making ethylene glycol comprising reacting synthesis gas, i.e. a mixture of carbon monoxide and hydrogen, plus formaldehyde in the presence of a homogeneous liquid catalyst containing an effective amount of cobalt-containing compound and a silicon or germanium-containing promoter and a solvent at a temperature of at least 50 DEG C. and a pressure of at least 500 psi wherein said ethylene glycol product separates as a separate liquid phase from the solvent.

标 题 :Process for low pressure synthesis of ethylene glycol from synthesis gas plus 1,3-dioxolane
发明人：KNIFTON JOHN F
权利人:TEXACO INC
摘要:This invention relates to the manufacture of ethylene glycol and more particularly to a low pressure process for making ethylene glycol comprising reacting synthesis gas, i.e. a mixture of carbon monoxide and hydrogen, plus 1,3-dioxolane in the presence of a homogenous liquid catalyst containing an effective amount of cobalt-containing compound and a silane or germane-containing promoter dispersed in a hydrocarbon solvent at a temperature of at least 50 DEG C. and a pressure of at least 500 psi, where the particular solvents used allow the desired product to be separated from the reaction mixture by phase separation.

权利人:BROMINE COMPOUNDS LTD
摘要:The present invention discloses a process for the preparation of highly pure pentabromobenzyl bromide, PBB-Br, wherein the benzylic bromination reaction is carried out in a suitable organic solvent in the presence of water and wherein the reaction temperature is such that it is sufficient to activate the initiator but not high enough to consume a substantial amount thereof.

权利人:TEXACO DEVELOPMENT CORP
摘要:A process for the production of mixtures containing ethylene glycol by reacting carbon monoxide, hydrogen and formaldehyde or 1,3-dioxolane at a temperature of at least 50°C and a pressure of at least 3.5 MPa in the presence of a cobalt catalyst, characterised in that the catalyst is a homogeneous liquid catalyst comprising cobalt, a halogen-free silicon compound having at least one carbon-­silican bond, and a solvent comprising an aromatic hydrocarbon or halohydrocarbon, a halo aromatic ether, a cyclic ether, or an excess of 1,3-dioxolane reactant.
