Description
United States Patent 3,210,277 STABILISATION OF CHLORINATED HYDROCARBONS George Edward 'Swift, Buncorn, England, assignor to Imperial Chemical Industries Limited, London, England, a corporation of Great Britain No Drawing. Filed Aug. '10, 1964, Ser. No. 388,720 Claims priority, application Great Britain, Aug. 26, 1963, 33,698 63 Claims. (Cl. 252-417) The present invention relates to the stabilisation of chlorinated hydrocarbons. More particularly it relates to the stabilisation of liquid chlorinated long chain paraffinic hydrocarbons for use as oil additives.
It is known to improve the properties of mineral oil lubricants when working under heavy loads by incorporating therein a proportion of relatively involatile liquid chlorinated paraflinic hyrocarbon, for instance a paraflinic hydrocarbon containing at least eight carbon atoms per molecule and chlorinated to a chlorine content of at least 25% by weight, particularly 4070% by weight. Although the extreme pressure lubricant properties of mineral oils are considerably improved by such additions, the improved lubricants are found to have the disadvantage of staining metal surfaces with which they come into contact in use, as for instance in metal cutting and drawing operations and in lubricated gear assemblies.
We have now found that the aforementioned disadvantage can be avoided by incorporating in chlorinated parafiins that are to be employed as oil additives a stabiliser system comprising a barium, calcium or magnesium alkyl phenate and a sequestering agent.
According to the present invention a stabilised lubricating oil additive comprises at least one liquid chlorinated parafiinic hydrocarbon containing 826 carbon atoms per molecule and at least 25% by weight of chlorine, 0.1-5 of a barium, calcium or magnesium alkyl phenate as hereinafter defined and 0.15% of an oil-soluble sequestering agent for heavy metals, the percentages of the said phenate and the said sequestering agent being calculated on the weight of chlorinated paraflinic hydrocarbon.
The barium, calcium and magnesium phenates employed in the present invention have in their simplest form the structure:
Where M is an atom of barium, calcium or magnesium, R is hydrogen or an alkyl group containing 1-10 carbon atoms, and R is an alkyl group containing 1-10 carbon atoms. When R as Well as R is an alkyl group R will usually be the same as R since such compounds are the more easily prepared. The phenate employed may, however, contain additionally a proportion of sulphur in the form of a single sulphur linkage or a dithio linkage between the two aromatic nuclei. The formulae of such phenates may be represented by the following two structures I and II, such compounds being alternatively known as alkyl phenol sulphides and disulphides:
3,210,277 Patented Get. 5, 1965 O l I R1 R1 Eta %112 where M, R and R are as defined in the preceding paragraph.
Suitable sequestering agents are for instance the pentaerythritol esters of long chain fatty acids, such as oleic, stearic and lauric acids, and the alkyl and aryl phosphites.
The alkyl phenate and the sequestering agent may each useful-1y be employed to the extent of 5% by Weight of the chlorinated paraflinic hydrocarbon, although for most applications 0.l1% by weight will be found to give adequate protection against metal staining. Greater amounts than 5% by weight may be employed but such amounts give no technical advantage and in general they are not economic.
As stated hereinbet'ore, chlorinated paraflinic hydrocarbons containing 826 carbon atoms per molecule and at least 25 by weight of chlorine may be employed in the stabilised lubricating oil additives of the invention. Of this range of compounds we prefer to employ for most applications those containing 40-70% by weight of chlorrne.
It is already known to add stabilisers to chlorinated hydrocarbons of the aforesaid range for the purpose of inhibiting decomposition by heat. It must be understood that chlorinated hydrocarbons stabilised according to the present invention may additionally contain conventional heat stabilisers, for example epoxidised oils.
We have found that if 0.15% by weight of a barium, calcium or magnesium alkyl phenate is added to the chlorinated hydrocarbon without an accompanying sequestering agent the staining of metal surfaces is prevented but that the heat stability of the chlorinated hydrocarbon (as determined by the standard test of measuring hydrogen chloride evolution on blowing nitrogen through the material heated for 4 hours at C.) is thereby reduced, even when conventional heat stabilisers such as epoxidised oils are present. We have found, however, that addition of an oil-soluble sequestering agent for heavy metals prevents this deleterious eifect, possibly by inactivating barium, calcium and magnesium chlorides which are thought to be formed in traces in the respective mixtures and to have a catalytic effect on decomposition of the chlorinated hydrocarbon.
The invention is illustrated by the following example but is not limited thereby. A mixture of C C paraflins chlorinated to a chlorine content of 65% by weight and containing 1% by weight of epoxidised oil as heat stabiliser is stabilised according to the present invention by addition thereto of 0.25% of barium octyl phenol sulphide and 0.25% of pentaerythritol dioleate, the percentages being calculated on the weight of chlorinated paraffins. The stabilised chlorinated parafl'ln, when added in amount of 40% by weight to a mineral cutting oil provides a heavy duty cutting lubricant which gives no noticeable staining of ferrous meta-1 parts.

1. A stabilized lubricating oil additive which consists essentially of at least one liquid chlorinated parafiinic hydrocarbon containing 8-26 carbon atoms per molecule and about 25 to 70% by Weight of chlorine, 0.l5% of a metal alkyl phenate wherein said metal is selected from the group consisting of barium, calcium and magnesium, and 0.15% of an oil-soluble sequestering agent for heavy metals, the percentages of said phenate and said sequestering agent being calculated on the weight of said chlorinated paraffinic hydrocarbon.
