'FINISH-REMOVER.

No Drawing.

To all whom it may concern Be it known that I, CARLETON ELLIS, a citizen pf the United States, and resident of Montclair, county of Essex, and State of New Jersey, have made a certain new and useful Invention Relating to Finish-Removers, of which the following is a specification.

This invention relates especially to finish removers comprising phenol camphor or similar compounds, together with incorporated volatile organic solvent material and waxy or other suitable stifi'ening material if desired. Various solid camphor terpenes have the peculiar property of combining with phenols in definite proportions so as to form compounds which have distinctive properties Widely different. from the com-.

ponents used. Ordinary laurel camphor, Borneol camphor and the turpentine camphors or their derivatives may be combined in this way with carbolic or cresylic acids. For instance, pure crystallized carbolic acid vwhich melts at 43C. when combined with laurel camphor which melts at 175 C. forms a liquid solvent. melting much below zero.

Such combinations may be effected when the I -stance, these camphorate solvents may be first formed and then incorporated with other remover ingredients or may be conveniently formed by bringing the components together in solution with the other remover ingredients. These camphoric terpenes seem to combine most readily in equimolecular proportions, although not only a camphorate but a bicamphorate can be formed with carbolic acid or with other phenols, such, for instance, as cresylic acid. These compounds are heavy liquids having .a very general and desirable solvent action on many paint or varnish gums, resins or binders so as to be desirable components for finish removers. It is also desirable to incorporate a suitable small proportion of such practically non-volatile material in removers to prevent any possibility of the drying out of finish on which waxy removershave actedto soften or,loosen the same.

Specification of Letters Patent. Patented Nov 24, 1914, Application filed April 1, 1912. Serial No. 687,770.

In this way even under extreme service conditions it is practically impossible for the wax or treated finish to form an undesirably hard coating even if allowed to stand for unusually long periods.

The main remover solvents may comprise loosening. finish solvent material, that is solvents of a generally alcoholic character or action in removers, such as methyl, ethyl,

propyl, butyl, benzyl and other strict alcopenetrating finish solvent material may also e be used, that is solvent material of a gen erally benzolic character or action 1n remqw'g.- ers, such as benzol and its homologues,

toluol, xylol and their commercial forms, such as commercial toluol, solvent naphtha;

and the somewhat analogouspetrolemnnydrocarbons, such as naphtha and benzin and the chlorinated derivatives, such as' chlorbenzol, chlortoluol and other chlorinated solvents, such as carbon-tetrachlorid, tetrachlorethane and the like, and also turpentine, wood turpentine and various esters an .pentine, pine oil and so forth,;by nascent hydrogen as by agitation of the solvent with sodium, potassium or the like or by other treatment with hydrogen in the presence of active metallic material, such as platinum,

d ethers, such as: bet'anaphthol ether, benzyl.

palladium and so forth. Suitable heavy solvents, such as may be used to minimize any tendency to drying out of the remover may comprise epichlorhydrin, dichlorhydrin or chlorinated lycerole or ethyl or methyl phenates. thyl phenate and methyl phenate and the corresponding cresylates are also desirable solvents which may be conveniently produced in various ways, the combination of the components being facilitated by suitable catalytic material such as aluminum oxid, thorium oxid or the like at a temperature of 350 to 400" C. or so, the thorium oxid having especially desirable catalytic action in this connection and promoting the formation of these particular compounds when the components are brought together in this way.

Su1table stilfening material may be used in such removers preferably comprising suitable Waxy evaporation-retarding material, such-as parafiin, ceresin or other mineral wax, although beeswax and other waxy bodies may be used and also other stifiening material, such as cellulose esters, nitrocellulose, which may be used in the form of scrap celluloid which usually contains nitrocellulose and suflicient incorporated camphor to combine with phenol and form the camphorated solvents referred to. llnert stidening material may also be incorporated if desired, such for example as wood flour, starch, infusorial earth, whiting and the like, it being of course understood that the soluble thickeners are preferably methyl acetate, 20 parts of benzol, 10 parts of benzyl alcoholp l parts of laurel camphor, 10 parts of scra would-contain nitrocell ose, and about 4 parts of camphor,'6 artsof carbolic acid and 2 parts of parafin.
