Catalyst contains essentially iron and copper-free rare-earth metal halide or oxyhalide. Atomic ratio of rare-earth metal to iron or copper is superior to 10:1. In case of cerium-containing catalyst, catalyst has at least one more rare-earth element, amount of cerium present being less than 10 atomic % of the total amount of rare-earth elements. Advantageously, process is conducted at volumetric alkane, halogen, and oxygen supply rate above 0.1 and below 1.0 h -1 , while diluent selected from group including nitrogen, helium, argon, carbon monoxide or dioxide or mixture thereof is additionally used. Halogenated product is recycled while being converted into supplementary olefin product and olefin product is recycled in order to be converted into halogenated hydrocarbon product. Optionally, allyl chloride and ethylene are obtained via interaction of propane with chlorine source in presence of catalyst. EFFECT: increased productivity of process and improved economical characteristics. 26 cl, 1 tbl ÐÎÑÑÈÉÑÊÀß ÔÅÄÅÐÀÖÈß RU (19) (11) 2 284 984 (13) C2 (51) ÌÏÊ C07C 17/154 (2006.01) C07C 17/25 (2006.01) C07C 21/067 (2006.01) B01J 23/10 (2006.01) ÔÅÄÅÐÀËÜÍÀß ÑËÓÆÁÀ ÏÎ ÈÍÒÅËËÅÊÒÓÀËÜÍÎÉ ÑÎÁÑÒÂÅÍÍÎÑÒÈ, ÏÀÒÅÍÒÀÌ È ÒÎÂÀÐÍÛÌ ÇÍÀÊÀÌ (12) ÎÏÈÑÀÍÈÅ ÈÇÎÁÐÅÒÅÍÈß Ê ÏÀÒÅÍÒÓ (21), (22) Çà âêà: 2003136824/04, 23.04.2002 (30) Êîíâåíöèîííûé ïðèîðèòåò: 23.05.2001 US 60/293 ...

Double metal cyanide catalysts containing functionalyzed polymers

Номер: RU2183989C2
Автор: Би Ле-Кхак

FIELD: polymerization catalysts. SUBSTANCE: double metal cyanide catalysts suitable for epoxide polymerization is not crystalline from data X-ray powder diffractometry. Catalyst contains double metal cyanide compound, organic complexing agent, and 2-80% of a functionalyzed polymer or its water- soluble salt. Polyols prepared in presence of this catalyst have low degree of unsaturation, low viscosity, and lowered level high-molecular tail fraction. EFFECT: simplified preparation procedure. 4 cl, 3 dwg, 1 tbl, 13 ex зе сз гс ПЫы сэ (19) (51) МПК?
