A method is provided for preparing a mixture of lower aliphatic alcohols characterized by containing a substantial proportion of aliphatic alcohols having from 2 to 6 carbon atoms by reacting a mixture of carbon monoxide and hydrogen under suitable conditions of temperature and pressure in the presence of a catalyst comprising molybdenum, a metal from the group consisting of cobalt, iron and nickel, and copper, said catalyst being modified by the addition of a promoter from the class consisting of potassium, cesium and rubidium, said promoter being employed at a concentration ranging from about 1.8 to 13.0 micromoles of said alkali per square meter of surface area of said catalyst.

Production of C.sub.2 -C.sub.6 aliphatic alcohols

This invention concerns dispersant-VI improvers prepared by reacting a polyamine-derived dispersant with an oxidized ethylene-propylene polymer or ethylene-propylene-diene terpolymer. The products thus formed have a dispersancy superior to that obtained by separately blending the reactants in a lubricating oil. Also disclosed are oils containing the present dispersant-VI improvers.

4-nitroisoxazoles are prepared by reacting an alpha-nitroketone with a hydroximyl halide in the presence of a tertiary amine.

Preparation of 4-nitroisoxazoles

A method for preparing alkane diamines by initially reacting a vicinal nitroketone with a primary amine hydrochloride thereby forming a nitroalkyliminoalkane or a nitrooximinoalkane and thereafter catalytically hydrogenating the nitroalkylimino- or nitrooximinoalkane to a diamine.
