Definitions
- This invention pertains to a new composition of matter prepared by reacting a mixture of two different alcohols with phosphorus pentasulfide (P285).
- this invention pertains to the zinc salts of a reaction product containing mixed diesters of dithiophosphoric acids pre pared by reacting phosphorus pentasulfide with a mixture or" two different alcohols (one alcohol containing not more than 4 carbon atoms, and the other alcohol containing from 6 to 18 carbon atoms).
- compositions set forth herein are useful in additives in lubricating oil compositions; particularly useful in inhibiting oxidation of lubricating oil compositions. These new compounds are remarkably efiective in increasing the useful life of a lubricating oil composition which is susceptible to oxidation.
- zinc salts of dialkyldithiophosphoric acids inhibit oxidation of lubricating oil compositions.
- the alkyl groups of these zinc dialkyldithiophosphates may be or" high molecular weight or low molecular weight.
- Zinc dialkyldithiophosphates, wherein the alkyl groups are the same and each contain less thanil carbon atoms (e. g, 4 carbon atoms) are considerably less expensive than the zinc dialkyldithiophosphates containing alkyl groups which are the same and derived from higher molecular weight alcohols.
- dialkyldithiophosphoric acids using two unlike low molecular weight alcohols as the source of the ester groups, and the zinc salts thereof.
- a further object of this invention is to prepare relatively low cost mixed diesters of dithiophosphoric acids.
- One of the alcohols used in the reaction contains less than 4 carbon atoms.
- These alcohols include methyl alcohol, ethyl alcohol, propyl alcohol, isopropyl alcohol, butyl alcohol, sec-butyl alcohol and tertiary outyl alcohol.
- this group of alcohols will hereinafter be called the R1 alcohols.
- the other alcohol used to form the reaction product of this invention contains from 6 to 18 carbon atoms. These include the following alcohols: hexyl, methylisobutylcarbin-ol, ethylisopropropylcarbinol, heptyl, iso-heptyl, Z-ethyl amyl, octyl, iso-octyl, 3-ethyl hexyl, Z-propyl amyl, decyl, undecyl, dodecyl, hexadecyl, octadecyl, etc.
- this group of alcohols will hereinafter be known as the R 2 alcohols.
- R1 and R: alcohols need not be present in the reaction mixture in equal molar amounts.
- the mole ratio of R1 aloe-- hols to R2 alcohols be from 1 to 5. It is particularly preferred to use a mole ratio of R1 alcohols to R2 alcohols from 2 to 4.
- the reaction products of this invention are normally prepared by mixing two different alcohols, and causing the mixture of alcohols to react with phosphorus pentasulfide (PzSs) at temperatures ranging from about 120 15. to 200 F.
- PzSs phosphorus pentasulfide

Serial No. 218,281
6 Claims.
This invention pertains to a new composition of matter prepared by reacting a mixture of two different alcohols with phosphorus pentasulfide (P285). In particular, this invention pertains to the zinc salts of a reaction product containing mixed diesters of dithiophosphoric acids pre pared by reacting phosphorus pentasulfide with a mixture or" two different alcohols (one alcohol containing not more than 4 carbon atoms, and the other alcohol containing from 6 to 18 carbon atoms).
ihe new compositions set forth herein are useful in additives in lubricating oil compositions; particularly useful in inhibiting oxidation of lubricating oil compositions. These new compounds are remarkably efiective in increasing the useful life of a lubricating oil composition which is susceptible to oxidation.
It is known that zinc salts of dialkyldithiophosphoric acids (wherein the alkyl groups are derived from the same alcohol) inhibit oxidation of lubricating oil compositions. It is also known that the alkyl groups of these zinc dialkyldithiophosphates may be or" high molecular weight or low molecular weight. Zinc dialkyldithiophosphates, wherein the alkyl groups are the same and each contain less thanil carbon atoms (e. g, 4 carbon atoms), are considerably less expensive than the zinc dialkyldithiophosphates containing alkyl groups which are the same and derived from higher molecular weight alcohols. In spite of this, these zinc dialkyldithiophosphates having alkyl groups derived from low molecular weight alcohols (e. g., alcohols of 4 carbon atoms) have not been widely marketed as lubricating oil additives. The main reason for this has been the insufiicient oil solubility of the zinc salts of low molecular weight dialkyldithiophosphoric acids to be able to prepare and market a concentrate in oil. This inability to ship concentrated oil solutions of these zinc salts due to the oil insolubility at normal storage conditions has more than offset the low cost of compounds per se. The same difiiculty of solubility pertains to the dialkyldithiophosphoric acids from which these zinc salts are derived.
It is'a primary object of this invention to prepare dialkyldithiophosphoric acids using two unlike low molecular weight alcohols as the source of the ester groups, and the zinc salts thereof.
It is another object of this invention to prepare zinc salts of: diesters of dithiophosphoric acids wherein the organo portions are derived from low molecular weight alchols, the dithicphosphates having sufficient oil solubility to prepare concentrated solutions of the zinc salts in oil of at least 35% at -20 F.
A further object of this invention is to prepare relatively low cost mixed diesters of dithiophosphoric acids.
These and further objects of the invention will be apparent from the ensuing description and the appended claims.
It has been discovered that the products obtained by the reaction of two different alcohols with phosphorus pentasulfide, and the zinc salts thereof, possess new and unique properties.
One of the alcohols used in the reaction contains less than 4 carbon atoms. These alcohols include methyl alcohol, ethyl alcohol, propyl alcohol, isopropyl alcohol, butyl alcohol, sec-butyl alcohol and tertiary outyl alcohol. For convenience, this group of alcohols will hereinafter be called the R1 alcohols.
The other alcohol used to form the reaction product of this invention contains from 6 to 18 carbon atoms. These include the following alcohols: hexyl, methylisobutylcarbin-ol, ethylisopropropylcarbinol, heptyl, iso-heptyl, Z-ethyl amyl, octyl, iso-octyl, 3-ethyl hexyl, Z-propyl amyl, decyl, undecyl, dodecyl, hexadecyl, octadecyl, etc. For convenience, this group of alcohols will hereinafter be known as the R 2 alcohols.
The R1 and R: alcohols need not be present in the reaction mixture in equal molar amounts. For certain types of oils and for certain purposes it may be preferred that the mole ratio of R1 aloe-- hols to R2 alcohols be from 1 to 5. It is particularly preferred to use a mole ratio of R1 alcohols to R2 alcohols from 2 to 4.
The reaction products of this invention are normally prepared by mixing two different alcohols, and causing the mixture of alcohols to react with phosphorus pentasulfide (PzSs) at temperatures ranging from about 120 15. to 200 F. For example, in the preparation or a reaction product of this invention, l moles of the desired alcohols (e. g., 3 moles of methyl alcohol and 1 mole of hexyl alcohol, wherein the mole ratio of methyl alcohol to hexyl alcohol is 3) are reacted with 1 mole of P285 for a time sufiicient to com-- plete the esteriiication. The zinc salts of the reaction mixtures are prepared by reacting the dialkyl dithiophosphoric acid preparation with Zinc oxide or zinc hydroxide at temperatures ranging from F. to 1'70 F.
The following examples illustrate methods of preparing the new compositions of this invention.
A mixture of 252 parts by weight (67 mole percent) of isopropyl alcohol and 206 parts by Weight (33 mole percent) of methyl isobutylcarbinol was placed in a glass reaction vessel. To this mixture was added 333 parts by weight of P2S5. The whole mixture was heated at 170 F. for 2 hours, after which the reaction mixture was cooled, and the product filtered to remove a small amount of unreacted P235.
In the preparation of the zinc salt, 650 grams of the acid intermediate thus obtained was added to 130 parts by weight of a petroleum oil having a viscosity of 300 SSU at 100 F. (used as a diluent), then 122 parts by weight of zinc oxide was gradually added at 130 F. The whole mixture was then agitated for 3 hours at 130 F., after which the water of neutralization was removed with calcium sulfate. The oil solution of the zinc salt had a pH of 6.? (after filtration), and contained 9.96% zinc, 9.43% phosphorus and 19.42% sulfur.
Example 2.--Reaction product of but'yl alcohol, methyiisobutylcarbinol and PzSs A mixture of 237 parts by Weight (7'? mole percent) or" sec-butyl alcohol and 98 parts by weight (23 mole percent) of methylisobutylcarbinol and 222 parts by weight or P285 was charged to a reaction vessel and agitated at 170 F. for a period of 2 hours. The reaction mixture was cooled and filtered to remove a small amount of unreacted P2S5. The resulting butyl methylisobutylcarbinol dithiophosphate was a dark red green liquid having a neutralization number of 193 (mgs. KOl-l/grarn), a viscosity of 35.7 SSU at 100 F., a specific gravity of 1.04 (60/60), and contained 24.0% sulfur and 11.9% phosphorus.
To the above mixture was added 87 parts by weight of zinc oxide, after which the whole was heated with agitation at 130 F. for 4 hours until a pH of 6.7 was reached. After the water of neutralization had been removed, the oil solution contained 7.6% zinc, 7.2% phosphorus and 15.0% sulfur.
The oil solubility of the zinc salts of this invention wherein the two different alcohols have certain mole ratios to each other is considerably greater than zinc salts having the same mole ratio of a mixture of two diester dithiophosphoric acids (wherein the ester groups in each acid are the same; that is, each acid contains only one of the ester radicals of the above mixed diester dithiophosphoric acid). For example, a 35% petroleum oil solution of a mixture of zinc di(secbutyl) dithiophosphate and zinc di- (methylisobutylcarbinol) dithiophosphate (mole ratio of 3.35) began to crystallize from solution within a period of 2 days at F. On the other hand, an 81% oil solution (same oil as above) of the zinc salt of the reaction product prepared according to Example 2 above was still clear after days at 20 F. Similarly, an 8% petroleum oil solution of a mixture of Zinc diisopropyl dithiophosphate and zinc di(methylisobutylcarbinol) dithiophcsphate (mole ratio of 2) began to crystallize from solution Within 3 days at +30 F. However, an 85% petroleum oil solution of the zinc salt prepared as in above Example 1 did not show any signs of crystallization after 34 days at +30 F.
The table below presents data concerning the effec 'veness oithe reaction products of this invention in reducing corrosion of metal parts due to oxidation of lubricating oils during the operation of internal combustion engines. To obtain these data, a stock Chevrolet engine was used. Instead of the normal babbitt bearings of -r in the Chevrolet engine, two of the connecting rods were modified to accommodate copper-lead bearing inserts, which were weighed before being assembled in the engine. The Chevrolet engine was operated at 3150 R. P. M., the engine jacket temperature was maintained at 300 F., the crankcase oil temperature was maintained at 280 F'., and the engine was operated for a period of 38 hours before being disassembled and the bearing inserts weighed. Before weighing, the bearing inserts were carefully washed with solvents to remove the oil therefrom.

The inhibition period (the time in hours before grams of oil sample utilizes 1000 cubic centimeters of oxygen at 340 F.) of a medicinal white oii zero hours. When 0.19% of the zinc salt of above Example 2 was added to the medicinal white oil, the inhibition period was increased to 4.2 hours.
