Patented Aug. 29, 1944 CLEANING COMPOSITION AND PROCESS Max I. Bowman and Howard Packer, Dayton, Ohio No Drawing. Application February 12, 1943 Serial No. 475,674
(Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) 3 Claims.
The invention described herein may be manufactured an used by or for Government for governmental purposes, without the payment to us of any royalty thereon.
This invention relates to solutions for the removal of foreign matter from surfaces such as metals, glass, porcelain and similar hard surfaces. More particularly, the invention relates to an improved solution of a combination of chemicals for the removal of carbon, grease, paint, dirt and other foreign matter from the surfaces of the various elements of internal combustion engines, electric motors, machinery, etc.
Heretofore, cleansing agents have been lacking in chemicals which will prevent pitting, tarnishin or the corrosion of surfaces to be cleaned. The damaging effects of such agents necessitate frequent replacement of parts.
A primary, but not limited, object of the invention is to provide a readily applicable means for th rapid and effective removal of carbonaceous material from pistons, rods, bearings,.
Percent by volume From- To- Aromatic solvents 30 60 Aliphatic amines, preferably amino alcohols such as monothanolamine, diethanolamine, etc 20 Fatty acids 10 20 Polyalcohols 5 20 Aromatic amine fraction r 5 20 Corrosion inhibitors with the anti-corms acteristics of organo-silicates plus organo-phosphates O. 30 2 A specific formula of the following specie of the generic combination has been found most satisfactory:
The specific combination of chemicals found most satisfactory is substantially as follows, with approximate proportions:
Per cent by volume Neutral coal tar oil (dead oil) 40 Morioethanolamine 15 Oleic acid 15 Ethylene glycol 15 Ortho-toluidine 15 Ethyl silicate .5 Phosphoric acid .5
In practice, the cleansing solution described has been proven to have less corrosion effect on metal parts such as steel, aluminum, magnesium, copper and alloys, than other carbon removers now available.
The neutral coal tar oil of the combination is a creosote oil from which most of the phenolic constituents are removed. This element of the combination is considered an advantage since it is less expensive than straight creosote oil, and since the valuable phenolic constituents, which have varied other uses, are critical materials in war time, and may thus be conserved for other purposes, Furthermore, coal tar oil is much less toxic than creosote oil.
The improved solution described contains no highly volatile constituents, and may be used at from to F., much higher temperatures than those at which most other cleansing agents may be used. This is considered an advantage since use of solutions at high temperatures increases the speed of the reactions involvrd.
The improved solution has proven to retain chemical stability and effectiveness, and has proven to produce corrosion resistance over a considerably longer period of time than cleansing agents of the character conventionally used.
As far as is known, neutral coal tar oil has never been substituted for creosote oil in cleansing agents, and it is further believed that ethylene glycol is a new factor in cleansing agents, particularly carbon removers. Likewise, as far as is known, ethyl silicate and phosphoric acid or amino-phosphates, have never been utilized as an inhibitor singly or in combination, as an element of cleansing agents, particularly adaptable for the removal of carbon, nor have aromatic amines been utilized in combination with other agents of the character of the foregoing formulas for cleansing agents, particularly for carbon removal.
Having described our-invention, and set forth generic, as well as specific, formulas by which the .same may be practiced, what we claim is:
1. A cleaning composition for the removal of foreign matter from metal, glass, and similar hard surfaces, said composition comprising a solution of which approximately 40 percent by volume is a neutral coal tar oil, of which approximately percent by volume is monoethanolamine, of which approximately 15 percent by volume is oleic acid, of which approximately 15 percent by volume is ethylene glycol, of which approximately 15 percent by volume is orthotoluidine, of which approximately .5 percent by volume is ethyl silicate, and of which approximately .5 percent by volume is phosphoric acid.
2. The process of cleaning machinery parts and similar hard surfaces of foreign matters such as carbon, grease, paint, dirt and the like which process consists of applying thereto a composition comprising the following chemicals in the following proportions by volume: neutral coal tar oil, approximately percent; monoethanolamine, approximately 15 percent; oleic acid, approximately 15 percent; ethylene glycol, approxizgately 15 percent; ortho-toluidine, approximately 15 percent; ethyl silicate, approximately .5 percent; and phosphoric acid, approximately .5 percent, and thereafter removing the reaction product resulting from the applied composition in combination with the said foreign matters to be removed.
3. A cleaning composition comprising a mixture of the following: 30 to percent by volume of neutral coal tar oil, 10 to 20 percent by volume of an amino alcohol selected from the group consisting of monoethanolamine, diethanolamine and triethanolamine, from 10 to 20 percent by volume of oleic acid, from 5 to 20 percent by volume of ethylene glycol, from 5 to 20 percent by volume of ortho-toluidine, and from .30 to 2% by volume of a corrosion inhibitor consisting of substantially equal quantities of ethyl silicate and phosphoric acid.
