Abstract
Extreme pressure lubricants comprise mineral oils having incorporated therein sulphurized esters obtained by reacting sulphur with unsaturated esters of mono- or di-hydric aliphatic alcohols with naturally occurring fatty acids having from 16 to 24 carbon atoms, the alcohol and/or acid radicals being unsaturated, in the presence of a secondary amine of the aliphatic, alicyclic or reduced heterocyclic series (see Group IV (b)). Examples describe as additives the sulphurized glycol, allyl and oleyl esters of rape seed acids, sperm oil and triethylene glycol and ethyl esters of soya fatty acids, dicyclohexylamine being used as activator in their preparation. Specification 588,353 is referred to. The Provisional Specification describes as additives, the products obtained by reacting sulphur with the mono- or di-hydric alcohol esters of naturally-occurring unsaturated aliphatic acids having 18 to 24 carbon atoms, preferably in presence of the above-mentioned activators.ALSO:Sulphurized esters are prepared by reacting sulphur with unsaturated esters of mono- or di-hydric aliphatic alcohols with the naturally occurring fatty acids containing 16 to 24 carbon atoms, in the presence of secondary amines of the aliphatic alicyclic or reduced heterocyclic series as activators. The alcohols and/or the acids may be unsaturated. At least 12 1/2 per cent by weight of sulphur may be used. The reaction is generally carried out at from 130 DEG to 180 DEG C. The products are extreme pressure additives for use in lubricating oils (see Group III) and have the same properties as the sulphurised glycerides described in Specification 588,353, [Group III]. In examples, sulphurised products are prepared from the glycol, allyl and oleyl esters of rape seed acids, sperm oil, and the triethylene glycol and ethyl esters of soya fatty acids, using dicyclohexylamine as the activator in each case. According to the Provisional Specification, liquid sulphurized products may be prepared by reacting sulphur with mono- and di-hydric alcohol esters of naturally occurring unsaturated aliphatic acids having 18-24 carbon atoms, preferably in presence of the above-mentioned applicators.
