Description

Patented May 13; 1930 m wa FREDERICK L. KOETHEN,. F NIAGARA FALLS, YORK, ASSIGNOR 'IO AGHESON GRAPHITE COMPANY,.OF NIAGARA FALLS, NEW YORK, A CORPORATION OF NEW JERSEY No Drawing.
' The invention relates toglubricants of ima red-mineral oil of 200 seconds at 100" F. on
the Saybolt universal instrument. This oil has a specific gravity of .905. I have found that the use of iron soap greatly increases the lubricating quality of the oil. The pro? portion of the soap to the mineral oil'may be varied and I havefou'nd that as high as by weight of the total composition may be employed. a v To prepare a lubricating composition consisting of a mineral oil having a Saybolt. viscosity of 200 seconds at 100 F. with 145% of iron soap I proceed as follows: The starting material is an ordinar commercial soda soap which has been ma e in the ordinary Way from stock consisting of approximately 3 parts of stearineand 1 part of oleine, and the soap is. dissolved in an excess of hot water using roughly 5 times the weight of thesoap. The solution is "heated to a temperature between 90100 C. and into it is poured slowly with constant stiring a 10 solution of ferric chloride until there has been added approximately 18 pounds F601 for each 100- pounds of soda soaptaken at the start. Transposition takesplace which produces iron soap and sodium chloride. The precipitated soap iswvashed by decantation' until practicallv free from sodium chloride, then dried in t e presence of anequal quantity of the mineral oil mentioned above bl heating in a kettle to the boiling point.. fter dehys bring the iron-soap percentage down to that desired is added as quickly as possible with vigorous stiring.
The'iron soap separates out in very small solid particles after the composition has been chilled but ifthe manufacture iscarried' out as described above theseparticles stay in suspension well enough for all practical purposes. However,. where it is desiring oil.

able tosecure more perfect suspension of the iron' soap particles, introduction of 210 soda soap will accomplish this result and will in no way affect the object sought, since the result obtained with the iron soap in the presenceof the soda soap are much superior to those obtained with soda soap alone.
1 In preparing the lubricant, the soap is not dissolved in the oil but is merely suspended in a very fine state of subdivision.
An emulsion containing a large amount of free water is-not contemplated in this invention.
I claim I p 1. A lubricating compound consistitn es-' sentially of iron soap and mineral lubr cat- 2. A substantially water-free lubricating composition comprising an iron soap and a lubricating oil.
3. A substantlally water-free lubricating composition comprismg an iron soap and a mineral lubricating oil. I a
