Definitions
- This invention relates to a lubricating oil composition for machineries such as compressors and the like.
- Compressed air used in association with health is usually produced by means of a combination apparatus of an oil cooling compressor and an oil mist filter-type compressor.
- the oil mist filter-type compressor is rarely employed in small and medium-sized manufacturing plants or in medical facilities, because the production costs of compressed air is almost twice the costs of that produced by an oil cooling compressor. These higher costs are due to the fact that the minimum economical capacity is about 15 KW.
- Examples of the fields in association with health in which compressed air is utilized include those in manufacture of food such as ice cream for stirring purposes, food treating facilities to skin vegetables such as onions by instantaneously blowing off the skin, breweries of bean paste and the like for stirring purposes, bottling of food such as soft drinks and beverages to blow off overflows, washing of bottles, transportation of powdery matters such as sugar, in portable air drills as an air source and for cleaning the throat for dentistry, and the like.
- Screw-type compressors have been commonly employed for the production of dried ice in medium to large scale plants to compress carbon dioxide.
- the lubricating oil used is strictly selected from the group consisting of innoxious lubricating oils in due consideration of being harmless to the human body because said lubricating oil is used under direct contact with the carbon dioxide gas.
- the lubricating oil is further required to have antioxidation properties because a very small amount of air may be mixed in with the carbon dioxide gas.
- the present invention is based on finding that a remarkable improvement in performances such as lubrication, rust prevention, and oxidation stability of an innoxious lubricating oil can be attained by incorporation of a specific compound in a specific amount into a liquid paraffin-based lubricating base oil.
- An object of the present invention is to provide an innoxious lubricating composition having improved lubricating properties, rust inhibiting properties, oxidation stability. More particularly, the present invention is to provide a lubricating composition comprising a major amount of liquid paraffin as a lubricating base oil and about 0.01 to 1.0 % by weight based on the total amount of the lubricating oil composition of saturated fatty acids having 12 to 22 carbon atoms as an essential component.
- a liquid paraffin is employed as the lubricating base oil wherein the liquid paraffin having a kinematic viscosity of 7 to 160 cSt at 40 °C is preferred.
- An example of preferable liquid paraffins includes a highly refined light lube cut obtained from crude oil by vacuum distillation followed by sulfuric acid treating.
- saturated fatty acids having 12 to 22 carbon atoms natural fatty acids or synthetic fatty acids may be employed, both straight and branched chain fatty acids are usable.
- saturated fatty acids include straight and branched chain fatty acids such as lauric acid, dodecylic acid, myristic acid, pentadecylic acid, palmitic acid, heptadecylic acid, stearic acid, nonadecanoic acid, arachic acid, and mixtures thereof.
- C14, C16, C18 or C20 fatty acid, and mixtures thereof are preferred.
- saturated fatty acids other than the acids having 12 to 22 carbon atoms or unsaturated fatty acids are employed in the place of the saturated fatty acids having 12 to 22 carbon atoms, performances such as oxidation stability and lubrication are unsatisfactory.
- fatty acids of the present invention have been designated as odorants in the legal definition of the term "food additives” and sorted into one of the standard raw materials used in the production of cosmetics and it is clear that they are perfectly innoxious to the human body.
- Said C12 to C22 saturated fatty acids are in an amount of about 0.01 to 1.0 % by weight based on the total amount of the composition, preferably about 0.01 to 0.5 % by weight. When the content is less than 0.01, performances such as oxidation stability, rust prevention and lubrication are insufficient, and there is no reward to incorporate the acids in an extra amount beyond the range.
- a lubricating oil composition having various improved performances may be provided by incorporation of saturated fatty acids having 12 to 22 carbon atoms as an essential component with a major amount of liquid paraffin as the lubricating base oil.
- dibutyl hydroxytoluene and/or tocopherol may be added further to improve the lubricating performances in the present composition.
- Dibutyl hydroxytoluene and/or tocopherol examples include 2,6-di-tert-butyl-4-hydroxytoluene, ⁇ -tocopherol, ⁇ -tocopherol, ⁇ -tocopherol, ⁇ -tocopherol, and mixtures thereof.
- antioxidants in the legal definition of the term “food additives”, and are completely harmless to human body.
- Dibutyl hydroxytolune and/or tocopherol is in an amount of 0.0001 to 5.0 % by weight, preferably 0.001 to 2.0 % by weight, more preferably 0.001 to 0.1 % by weight based on the total amount of the composition.
- various other additives may be optionally used, in so far as they are not harmful to the human body.
- innoxious additives examples include higher fatty alcohols such as oleyl alcohol, animal and vegetable fatts and oils including their partially hydrogenated products, higher fatty acid esters such as methyl laurate and butyl stearate as an oiliness improver, tert-butyl-hydroxyanisol as an antioxidant, sorbitan fatty acid esters such as sorbitan monooleate, sucrose fatty acid esters such as sucrose monolaurate and the like as a corrosion inhibitor, and mixtures thereof.
- higher fatty alcohols such as oleyl alcohol, animal and vegetable fatts and oils including their partially hydrogenated products
- higher fatty acid esters such as methyl laurate and butyl stearate as an oiliness improver
- tert-butyl-hydroxyanisol as an antioxidant
- sorbitan fatty acid esters such as sorbitan monooleate
- sucrose fatty acid esters such as sucrose monolaurate and the like as a corrosion inhibitor
- these other additives are usually in an amount of less than about 20.0 % by weight respectively, preferably about 0.1 to 10.0 % by weight based on the total amount of the composition, said amount not being limited.
- compositions listed in Table 1 the lubricating compositions (Examples 1 to 6) of the present invention were prepared. Performance tests were carried out for these compositions by the following methods and the test results are set forth in Table 1. A blank test was run with a sample consisting of the same liquid paraffin used as the base oil, and the results are also set forth in Table 1
- the lubricating compositions of the present invention have improved performances of lubrication, rust prevention and antioxidation, and are completely innoxious to the human body.
