Improvements in and relating to the preparation of lubricating greases

A lubricating grease is prepared by dispersing a waterproofed clay or clay-like material in a lubricating oil in the presence of a polar organic compound miscible with the oil and having a dielectric constant greater than 10 at 20 DEG C. An increase in the gelling power of the clay, and a reduction in the milling necessary are obtained. The clay may be natural, particularly montmorillonite of high magnesia content, or synthetic clay or zeolite, e.g. made by coprecipitating silica and magnesia by adding magnesium chloride to potassium silicate solution, drying the gel, and heating with caustic soda at 240 DEG C and 450-550 p.s.i. to give a synthetic Hectorite. The magnesium chloride may be replaced by calcium, barium or aluminium chloride, and caustic soda by potash, ammonia or lithia. A preferred class of clays contains 2-20 per cent of alkaline-earth metal. The waterproofing may be effected by treating a clay hydrosol with a cationic surface active agent such as a quaternary ammonium compound or amine salt having at least one hydrocarbon radical of 12 or more carbon atoms or a partial amide of a fatty acid of at least 12 carbon atoms with a condensation product of ammonia or an amine with acrolein or its analogues or of ammonia with epichlorhydrin. The clay should contain at least 30 per cent by weight of hydrophobic surface active radicals. Another method of waterproofing clays comprises treating with a solution of a salt capable upon heating of forming basic salts, e.g. lead, barium or strontium salts of fatty acids, washing out unadsorbed salt and heating at 100-435 DEG C for 1-24 hours.

Homogenized composition of waxy depressants of fluidity loss point and method of homogenation of mixture

FIELD: chemical industry, more particularly dispersions of waxy depressants of fluidity loss point. SUBSTANCE: depressant composition comprises depressant which is solid at 10 C with average numerical molecular weight of at least 500 and liquid medium in which material of depressant of fluidity loss point is substantially insoluble at room temperature. Depressant component is dispersed in liquid medium. Depressant makes it possible to decrease solidification temperature to desired values using no solvents. EFFECT: improved properties of the homogenized composition. 16 cl, 9 ex САРАЕ сС ПЧ с» (19) РОССИЙСКОЕ АГЕНТСТВО ПО ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ ВО 2 171 272 51) МК’ С 10 1/18, 1/22 (13) С2 (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ (21), (22) Заявка: 96122562/04, 28.11.1996 (24) Дата начала действия патента: 28.11.1996 (30) Приоритет: 29.11.1995 $ 60/007,686 08.04.1996 ЦЗ 08/629,211 (43) Дата публикации заявки: 27.01.1999 (46) Дата публикации: 27.07.2001 (56) Ссылки: Ч$ 4565550 А, 21.01.1986. 4$ 4402708 А, 06.09.1983.

Aliphatic aldehydes and corresp. alcohols and esters - made by aldol condensn. using phase transmission catalysts

Novel aldehydes of formula:- (in which x and y are 0-4; R is 1-4C alkyl) and the corresp. satd. aldehydes and alcohols, together with di-esters from the alcohols and carboxylic acids of formula:- HOOC-(CH2)z-COOH, (in which x is 1-4 and z is 1-12) are prepd. by aldol condensn. of aldehydes of formula:- (CH3(CH2)xCHRCHO with aldehydes of formula:- CH3(CH2)yCH2CHO, in presence of aq. alkali metal hydroxide soln. and a phase transmission catalyst. The esters are suitable bases for synthetic lubricating oils, e.g. for jet and piston engines. Use of catalysts results in much higher yields nd conversion of the raw materials.
