Abstract
Oils derived from fatty hydroxyacids, or substances containing them, are heated with a polymerization catalyst, and the product is heated under reduced pressure with an alcohol, preferably in the presence of an esterification catalyst. The first treatment is effected at 150--300 DEG C. at atmospheric or somewhat raised or reduced pressure in the absence of alkaline compounds and alcohols and with or without the use of a current of inert gas; the polymerization catalyst may be a compound of an element of the third, fourth or eighth periodic group, and may be supported on active charcoal. As esterification catalysts in the second treatment, use may be made of esters of mineral acids, particularly sulphuric esters of alcohols and of organic hydroxyacids. According to the conditions, the products are partly or totally soluble in hydrocarbons and mineral oils; they may be used as lubricants, alone or with other lubricants. In the example, castor oil is heated with aluminium hydrosilicate at about 270 DEG C. and atmospheric pressure for a period not exceeding one hour, and the product is heated with a little glycerol to the same temperature at a pressure of about 20 mm. in the presence of hydroxyoleic acid sulphuric ester or other esterification catalyst. The Specification as open to inspection under Sect. 91 states that the two treatments may be effected in one operation, without isolation of the intermediate product, and that the treatments may be applied to free hydroxy fatty acids or mixtures containing them. It states also that organic or inorganic acids or acid salts may be added during the first treatment, and that an alcohol need not be added in the second treatment. It includes also a further example in which a mixture of colza oil and castor oil is heated to 190 DEG C. at atmospheric pressure with aluminium hydrosilicate, and the product is heated to 230 DEG C. in vacuo with glycerol in the presence of hydroxyoleic acid sulphuric ester. This subject-matter does not appear in the Specification as accepted.
