摘要:
Complex esters of the present invention are manufactured by making C.sub.3.sub.-30 olefin, carbon monoxide, polyalcohol and polycarboxylic acid react in the presence of a cobalt compound catalyst.
摘要:
In the method of manufacturing carboxylic acids or esters thereof by reacting olefin, carbon monoxide and alcohol or water in the presence of catalyst prepared in advance by heating a cobalt compound and pyridine or at least one pyridine base selected from the group of mono-, di- and tri-alkyl (having 1.about.3 carbon atoms)-substituted pyridines under the pressure of carbon monoxide.
摘要:
In the method of manufacturing liquid polyol esters of carboxylic acid by making an olefin having 3 or more carbon atoms, carbon monoxide and polyhydric alcohol react with one another in the presence of a cobalt compound catalyst, the steps comprising heating the thus reacted mixture to distill out unreacted olefin and so forth, thereafter cooling the distillation residue and separating it into the ester of polyhydric alcohol and the cobalt compound.
摘要:
An aqueous coal slurry composition is provided which comprises:(a) at least one compound selected from (a-1) a polyether polyol compound prepared by adding ethylene oxide and/or propylene oxide to an active hydrogen-containing compound, (a-2) a compound prepared by esterifying compound (a-1), (a-3) a compound prepared by phosphating, sulfating or carboxyalkylating compound (a-1) or a salt thereof, (a-4) a compound prepared by crosslinking compound (a-1) with a crosslinking agent, (a-5) a compound prepared by reacting compound (a-1) with epihalohydrin and (a-6) an isocyanate-terminated compound prepared by reacting compound (a-1) with a polyvalent isocyanate,(b) at least one surface active agent selected from (b-1) a sulfonation product of naphthalene or its salt or an aliphatic aldehyde addition condensate thereof, (b-2) an aliphatic aldehyde condensate of a sulfonic acid group-containing aminotriazine or its salt and (b-3) a sulfonation product of creosote oil or its salt or an aliphatic aldehyde addition condensate thereof,(c) water and(d) a coal powder.The aqueous coal slurry has good fluidity and static stability.
