6 Claims. (Cl. 25252) This invention relates to the production of oil -si derably above room temperature even in the that is particularly useful as a softening agent presence of moisture, and it can be cheaply manor lubricant for textile products although its use ufactured. is not limited to this particular purpose. In carrying out this invention castor oil isso Heretofore objections and difliculties have been treated that a product is obtained therefrom encountered when diiierent sorts of oils have been which has been found to possess the characteris- 'used as lubricants for textiles. Among the obtics mentioned above that make it particularly jections that have arisen have been the developsuitable as a lubricant for textiles without the ment of rancidity in the oils or discoloration of objectionable features heretofore encountered.

Some of the oils The castor oil is so treated that the hydroxy that have been used for this purpose are difllcult groups therein are first removed therefrom by deto remove, some arequite expensive and some do hydrating the castor oil until its iodine value is not possess the desired lubricating properties. about 140 whereupon the ricinoleic acid radicals Olive oil has heretofore proven to be one of therein become linoleic acid radicals. This may the most satisfactory oils for lubricating textiles be done in the ways already known such, for exas it possesses great lubricating power which enample, as by treating it with a non-oxidizing min- 15 ables the fibers that are lubricated with it to slide eral acid or other catalyst as mentioned in my over each other quite easily, and at the same application Serial No. 210,428 flied May 27, 1938.

This may as a textile lubricant. Some of the objections be accomplished, for example by treating the deto it are: it is not colorless as it contains iron hydrated product with hydrogen at atemperature and chlorophyl so that there is a tendency to stain of about 250 C. under pressure. In this way the the fabric, especially white fabrics; it possesses a linoleic acid radicals are changed for the most noticeable odor that is not pleasing to everyone part to oleic acid radicals, or an isomer thereof,

About 85% of castor oil consists of the glyceride of ricinoleic acid which has one double bond and an hydroxyl in its molecule. The dehydrating step appears to remove the hydroxyl and convert the ester into the glyceride of linoleic acid which has two double bonds, and the hydrogenation step appears to saturate one of the two double bonds in each linoleic acid residue in this ester thus converting it into the glyceride of oleic acid or an isomer thereof, with very little it any of the glyceride of saturated acids such as stearic acid or of the glyceride of acids having two double bonds such as linoleic acid therein.
What is claimed is:
'1. A lubricant for textiles and the like comprising dehydrated castor oil having one of the double bonds of each acid group saturated.
2. A lubricant for textiles and the like comprising dehydrated castor oil that has been subjected to about a fifty percent hydrogenation.
3. A lubricant for textiles and the like comprising dehydrated castor oil that has been hydrogenated until its iodine value is between about 80 and about 90.
4. The process of producing a lubricant for textiles and the like which comprises dehydrating castor oil and hydrogenating the dehydrated product until saturation of one of the double bonds of each acid group takes place.
5. The process of producing a lubricant for textiles and the like which comprises dehydrating castor oil and hydrogenating the dehydrated product until it is about half saturated.
6. The process of producing a lubricant for textiles and the like which comprises dehydrating castor oil and hydrogenatlng the dehydrated product until its iodine value becomes between about 80 and about 90.
