Description
scribed and claimed.
' stead ofTurkey re Patented June 30, 1931 UNITED STATES. PATENT OFFICE FREDERICK WILLIAM" ATAQ'K, OF KINGSTON, ONTARIO, CANADA, ASSIGNOR TO IN- DUSTRIAL PROCESSES DEVELOPMENT, LIMITED, OF TORONTO, ONTARIO, CANADA,
A CORPORATION OF CANADA EMULSION No Drawing. Application filed March 3, 1928, Serial No. 259,593, and in Great Britain April 19, 1927.
This invention relates to emulsions of grease solvents and to a process of manufacture thereof. The object is to provide emulsions which are fluent, i. e. immediately miscible with water, and yet are-stable. Further objects are to provide novel emulsions and detergent compositions containing grease solvents, notably chlorinated hydrocarbons.
whereby it is possible to obtain fluent emulsions of such solvents which are still stable. To this end the invention comprises the methods and compositions as hereinafter de- Example 1 By way of example, a suitable emulsion contains (parts by weight) The ammonia is added in the form ofa dilute solution in part of the water while the bentonite is previously suspended as an 8% sus ension in the remainder of the water.
ther emulsifyin agents may be used in oil, but it is desirable to avoid substantial quantities of gelatinizing ingredients such as common soap.
If substantial quantities of soap are used,-
a gelatinous composition is obtained which does not mix immediately with water, where,-
-as the product of the present invention is liquid and fluent and it immediately mixes with water. 7
Example 24 lbs. of bentonite aresuspended in 300 lbs. of water, 30 lbs. of Turkey red oil are v miscible with water contalmng a liquidchloadded, and 120 lbs. of triohlorethylene added stirring with water they can be transported with rapid stirring, lbs. of fatty acids are added with stirring, followed by suflicient alkali to give a slightly alkaline product (not over 4 lbs. of caustic soda solution). The object of added alkali is to guard against liberation of mineral acid from the chlorinated solvent. It is advantageous to begin with the mixture of water and bentonite as described.
The product is an aqueous emulsion of remarkable stability and even on great dilution gives stable emulsions." I
In this example the 120 parts of trichlorethylene may be replaced by a mixture of 90 parts of trichlorethylene and 30 parts of tetrahydronaphthalene.
The term bentonite is used to include colloidal siliceous materials having the characteristic bentonitic property, namely that by into a stable dispersion. The term chlorinated hydrocarbon includes hydrocarbons containing chlorine whether prepared" by an actual chlorination process or not; trichlorethylene is only given by way of example. Other grease solvents maybe used, c. g..hydrogenated hydrocarbons or hydrogenated v phenols.
Among other uses for the novel emulsions, -80
they maybe employed as deter cuts in laundering, carpet cleaning, etc.;' or the scouring and finishing of wool; for kier-boiling and finishing of cotton goods; for scouring, dyeing and finishing of artificial silk in one bath process; for scouring, dyeing and finishing of mercerized cotton; for degumming ofsilk; as assistant in wetting out and level dyeing, especially of artificial silk; for deinkin of printed paper stock; and for gen eral detergent purposes, such as in dishwashing machines, household cleaning, paint cleaning etc.
The emulsions may also be mixed/ with solid materials and a useful detergent consists of a mixture of one part of the product of Example 1 or 2 with six parts of soda ash and-three parts of sodium bicarbonate.
I declare that whatI clai i v 1. A liquid aqueous emulsion immediately rinated hydrocarbon, Turkey red oil and bentonite, and exhibiting a weak alkaline reaction. 2. A liquid emulsion containing a liquid 5 chlorinated hydrocarbon in greater quantity than any other ingredient, water, Turkey red oil as primar emulsifier, bentonite, and a small proportlon'only of soap.
3. A stable liquid emulsion instantly mism cible with water, containing water, aliquid grease solvent substantially immiscible with water, a primary emulsifying agent which is a sulphonated product derived from. a glyceride and capable of forming a transient 15 emulsion instantl miscible with water, and
bentonite as a sta ilizer of said emulsion.
In witness whereof, I have hereunto signed my name this first day of March 1928.
FREDERICK WILLIAM ATACK.
