Abstract
Synthetic lubricants comprising 15 to 45 weight percent of an ester of a monohydric alcohol of 4 to 18 carbon atoms with one or more aromatic or alkane dicarboxylic acids having 4 to 18 carbon atoms blended with 85 to 55 weight percent of one or more polyether polyols having a number average molecular weight from about 400 to 5000. The blends are compounded with antioxidants, corrosion inhibitors, and metal deactivators to produce a superior lubricant for reciprocating air compressors which gives a long life to the compressors.
Description
This application is a continuation-in-part of Ser. No. 812,167 filed Dec. 23, 1985, now abandoned.
This invention relates to synthetic lubricants which are a suitably inhibited blend of (1) an ester of a monohydric alcohol having 4 to 18 carbon atoms with one or more aromatic or alkane dicarboxylic acids and (2) one or more polyether polyols.
Reciprocating air compressors having air cushioned valves are well known in the art.
It is well known to use hydrocarbon lubricating oils to lubricate the pistons and piston rings of the foregoing air compressors and lubricate the bearings. Due to the high temperature and pressure of the air, it has been found that these hydrocarbon oils break down, leave deposits, and prevent the valves from operating correctly in a relatively short time. This requires manual repairs to clean the valves.
It is known that synthetic esters made from dicarboxylic acids have been used to produce long lasting compressor fluids, such as Anderol 495 sold by Nuodex for rotary screw air compressors. The major component of Anderol 495 is believed to be a dialkyl adipate. However, Anderol 495 does not have sufficient high temperature viscosity for suitable lubrication of the pistons and cylinders of reciprocating air compressors.
It is also known from U.S. Pat. No. 4,302,343 that rotary screw air compressors can be lubricated with a blend of polyhydric alcohol esters and polyether polyols. However, these lubricants are relatively expensive and leave deposits on the valves of a reciprocating air compressor.
Anderol 500 (a dialkyl phthalate composition) is known to be useful in reciprocating air compressors. However, this synthetic ester has the disadvantage of having a high viscosity during start up at low temperatures.
The U.S. Pat. No. 4,072,619 polyesteralkylene glycol compositions are disclosed wherein phenothiazine is incorporated into the alkylene glycols. However, these compositions have been found to degrade in a relatively short time i.e. 1000 hours.
Synthetic lubricants comprising a major amount of a polyester and a minor amount of a monocapped polyglycol are known from British Pat. Nos. ,933,721; 986,066; and 1,162,818, however all these compositions are disclosed to be only useful in aircraft gas turbines where a different viscosity range is needed.
It now has been found that a suitably inhibited blend of esters of aliphatic monohydric alcohols with one or more aromatic or alkane dicarboxylic acids have the required high temperature viscosity and stability to heat, air, and water.
More specifically, the synthetic base lubricants of this invention comprise a lubricant composition comprising,
(A) about 15 to 45 weight percent of an ester of a monohydric alcohol having 4 to 18 carbon atoms with one or more aromatic or alkane dicarboxylic acids having 4 to 18 carbon atoms, and
(B) about 85 to 55 weight percent of one or more polyether polyols have a flash point greater than 375° F. (191° C.) and which have the formula
Z--[(--R.sup.1 O).sub.n R.sup.2 ].sub.m
where Z is the residue of a compound having 1-8 hydroxyl groups,
R1 is an alkylene radical having 2 to 4 carbon atoms,
n is a number having an average value which will give a number average molecular weight range from about 400 to about 5000 for the final compound,
m is an integer having a value of from 1 to about 8,
R2 is hydrogen or an alkyl group of 1 to 6 carbon atoms.
An additional aspect of the present invention comprises the above base lubricant with the addition of effective amounts of oxidation inhibitors, corrosion inhibitors, and metal or copper deactivators and a method of lubricating air compressors using the inhibited lubricant.
The neutral esters used in this invention are commercially available. Examples of suitable esters are the esters of monohydric alcohols having 4 to 18 carbons such as butanol, octanol, decanol, etc with aromatic dicarboxylic acids such as phthalic, terephthalic and isophthalic acids.
Also useful are the esters of the above monohydric alcohols with alkanedioic acids having 4 to 18 carbons such as succinic, adipic, suberic, tetradecane 1,14-dioic acid, and hexadecane-1,16-dioic acid,
Examples of the polyether polyols or polyoxyalkylene polyols used in this invention are those derived from ethylene oxide, propylene oxide, 1-2, or 2-3 butylene oxide. The above oxides may be polymerized alone, i.e., homopolymerized or in combination. The combined oxides may also be combined in a random or block addition. While some of the above compounds may be of a hydrophilic nature, those of a hydrophobic nature are preferred, such as those derived from propylene oxide, butylene oxides or combinations thereof.
Examples of suitable capped polyoxyalkylene glycols are those derived from ethylene, propylene, and butylene oxides wherein the alkylene oxides are initiated from a compound having 1 to 8 active hydrogens in a known manner. The terminal hydroxyl groups may be further reacted with organic acids to form esters or with alkyl or aryl halides to form alkyl or aryl capped polyoxyalkylene are well known from the book "Polyurethanes" by Saunders and Frisch, Interscience Publishers (1962), pages 33-39. This book is incorporated by reference herein.
Examples of suitable initiator compounds which are employed to prepare the above polyether polyols are compounds having 1-8 active hydrogens such as for example water, methanol, ethanol, propanol, butanol, ethylene glycol, propylene, glycol, butylene glycol, 1,6-hexane diol, glycerine, trimethylolpropane, pentaerythritol, sorbitol, sucrose, mixtures thereof and the like.
Other initator compounds which are useful include monohydric phenols and dihydric phenols and their alkylated derivatives such as phenol, o, m, and p cresol, guaiacol, saligenin, carvacrol, thymol, o and p -hydroxy diphenyl, catechol, resorcinol, hydroquinone, pyrogallol, and phloroglucinol.
The foregoing polyether polyols should have a flash point greater that 375° F. (191° C.) and preferably greater than 450° F. (232° C.). They also should have a number average molecular weight range from about 400 to 5000 and preferably in the range 700 to 2500.
The foregoing polyether polyols are blended to give a base lubricant composition containing 15 to 45 weight percent of the esters and 85 to 55 weight percent of the polyols with the ranges 15 to 25 and 85 to 75 being the preferred ranges, respectively.
The compositions of this invention are used in a reciprocating air compressor and are selected so as to have a viscosity in the range of 5 to 25 centistokes at 210° F. (99° C.) and preferably 6 to 16 centistokes at 210° F. (99° C.) and a pour point in the range of 0° to -65° F. (18° to -54° C.).
The final lubricant compositions of this invention may contain effective amounts of ashless additives, such as antioxidants, corrosion inhibitors, metal deactivators, lubricity additives, extreme pressure additives, dispersants, detergents, demulsifiers or such additives as may be required.
Examples of useful ashless antioxidants which can be used herein are phenyl naphthylamines, i.e., both alpha and beta-naphthyl amines; diphenyl amine; iminodibenzyl; p,p-dibutyl-diphenylamine; p,p'-dioctyldiphenylamine; and mixtures thereof.

An effective amount of the foregoing additives for use in a reciprocating air compressor is generally in the range from 0.1 to 5% by weight for the antioxidants, 0.1 to 5.0% by weight for the corrosion inhibitors, and 0.001 to 0.5 percent by weight for the metal deactivators. The foregoing weight percentages are based on the total weight of the polyether polyols and the esters. It is to be understood that more or less of the additives may be used depending upon the circumstances for which the final composition is to be used.
