Description
Patented Nov. 15, 1938 UNITED STATES PATENT OFFICE LUBRICATING OIL v Amato Furlottl, Milan, Italy 2 Claims.
This invention relates to a lubricating oil constituted by a stable solution in castor oil of min-- eral oil with a percentage'up to 10, 15% and even 25% of the latter according to the purpose 5 for which the oil is intended, and to a process for the preparation thereof.
The lubricating oil obtained according to this invention maintains the valuable properties of castor oil, some of which are even improved, so
for instance it is possible to lower the freezing point and raise the fiash point, while certain defects of the castor oil are practically eliminated or considerably reduced, such as for instance the formation of gums on the pistons of internal combustion engines, the disagreeable smell at the exhaust of said engines, acidity, etc.
The method of preparing the lubricating oil according to this invention does not require special apparatus and is efi'ected wholly in the cold, as distinct from other methods of incorporating mineral oil in castor oil; it consists essentially in thoroughly mixing in the cold both oils in the desired proportions with the addition of triethanolamine in the proportion of 0.1 to 5 parts to 1000 parts by weight of the oil mixture. This addition has the property of 5 making possible and stabilizing the solution of the mineral oil in castor oil.
In certain cases, with given types of mineral oils, it is possible to considerably increase the percentage of these oils in the solution beyond 10 the above mentioned limit.
What I claim is:
1. A lubricant being a solution of about 10 to per cent mineral oil in castor oil with an addition of triethanolamine as stabilizer.
2. The process of preparing a lubricant, which 15 comprises dissolving in cold state about 10 to 25 per cent mineral oil in castor oil in the pres ence of a quantity of triethanolamine ranging from about0.1 to 5 parts per thousand by weight.
