SU41103A1 - Method of making fabulous oils of low viscosity - Google Patents

Description

Lubricating oil should have as little internal friction as possible and as much as possible withstand pressure. Since in conventional mineral oils these two properties are directly proportional (the more viscous the oil, the greater its ability to withstand pressure), depending on the given operating conditions (load, speed, etc., you have to choose a certain oil, minimum permissible under these conditions, viscosity, obviously going to energy losses due to increased strength of friction.

In the U.S. practice, lubricants for emergency loads (E.P. | Li bricant) are known, which are used where the most viscous mineral, vegetable or animal oils and fats are not able to withstand pressure.

In a report reviewing polonsenn with extraordinary pressure lubricants in the United States at the XIII Congress of the American Petroleum Institute (Nov. 17, 1932) N. Wolt and N. Mougey write that the test of emergency press lubricants is where (64)

nor for the satisfactory lubrication does not require the ability to carry excessive loads, can not give any results. Thus, the use of such lubricants (for exceptional pressure) is very limited.

This invention has in mind

possibility to produce oils of low

viscous but capable

I withstand pressure and other

 properties to the extent that it’s your answer, but 3-4 times more

I butter.

I To change only the surface properties of the oil for better adherence to the metal, but without a significant change in the internal viscosity and coefficient of friction of the oil, according to the fed method, in low-viscosity mineral oils (steam oil, naphtha, kerosene, etc.) At 50 ° C, at 50, 1-5% of one of the chlorine derivatives of benzene or naphthalene, or mixtures thereof (monochlorobenzene, dichlorobenzene, etc.) are added, and this oil hardly increases its viscosity and at the same time becomes capable of replacing spun and light engine oils Yew, 5 ° E. With the introduction of the same chlorine derivatives in oil with a viscosity of 2.0-2.5 ° E, the resulting oil, again almost without changing its viscosity, can replace heavy mineral oils with a viscosity greater than 6 ° E.

The same effect is obtained with the introduction of the same viscosity of sulphurised (when heated) vegetable oil into mineral oil, not exceeding 20%, or sulfo-derived aromatic compounds from heavy fractions of oils, for example, paraffins, naphthenes.

In cases where, due to the design features of the lubricated mechanism, the leakage of low-viscosity oil could be too large or when the lubricant is applied to the scrub, the immersion of the surfaces is carried out with a WASH. And capillary media (wicks, ends, cloths, etc.). ), it is possible to use an oil manufactured according to the method described above and infused with the necessary alkaline or metallic soaps of certain organic acids commonly used for the manufacture of grease.

The subject matter of the invention.

Claims (3)

1. A method of preparing lubricating oils of low viscosity, intended by its properties for using them instead of more viscous lubricating oils, characterized in that, in order to increase only the surface properties of the oil necessary, for more dense adherence of the lubricant to the metal surface, but without significant changes at the same time of the internal viscosity and coefficient of friction of this oil, in light low-viscosity mineral oils (with a viscosity from 1.1 ° E to 4 ° E), no more than 5% of chloropromine benzene or naphthalene (for example, monochlorobenzo la, dichlorobenzene, etc.) or other similar hydrocarbons. 2. In the method according to claim 1, use for the same purpose no more than 20% of sulphurised when heated vegetable oil or sulfo derivatives of aromatic and unsaturated compounds of heavy mineral oils. 3. The use of lubricating oils obtained according to claim 1 for the manufacture of greases by thickening with methods commonly used for the manufacture of greases.
