UNITED STATES PATENT OFFICE.
OSKAR NAGEL, OFVIENNA, AUSTRIA-HUNGARY.
MANUFACTURE OF COMPOUNDS OF PYROXYLIN.
SPECIFICATION forming part of Letters Patent No. 596,662, dated January 4, 1898. Application filed February 3 1896. $eria1 No. 577,942- (No specimens.)
To all whom it may concern.-
Be it known that I, OSKAR NAGEL, a subject of the Emperor of Austria-Hungary, residing at Vienna, Austria-Hungary, have invented a certain new and useful Improvement in the Manufacture of Compounds of Pyroxylin, of which the following is a specification.
My invention relates to the manufacture of compounds'of pyroxylin by the use of a new solvent for nitrocellulose, which acts substantially in the'same manner as does gum-camphor I have discovered that the crystalline body formed by passing dry hydrochloric-acid gas through dry turpentine may be employed as a solvent for nitrocellulose either just as it is produced by passing the gas through the turpentine or after it has been subsequently treated to remove the hydrochlorid. The crystalline body produced by passing dry hydrochloric-aoid gas through anhydrous turpentine is known as hydrochlorinated turpene, (C H HGL) The body O H remaining after the hydrochlorid has been distilled 01f, as by the use of lime, is known as camphene. Either of these bodies may be used as a solvent for nitrocellulose in the same manner. Persons skilled in the art of producing pyroxylin compounds will readily understand the manner of working this solvent with pyroxylin, as there is no essential diiference between it and the mode of working gum-oamphor. However, as an example I will state that I prefer to dissolve the nitrocellulose in a suitable solventas, for instance, ethyl alcohol and etherin the proportions usually employed for dissolving nitrocellulose in the'manufacture of pyroxylin compoundsthat is to say, two parts of ethyl alcohol and eight parts of ether to dissolve ten parts of pyroxylin, all by weight. When the pyroxolin has been thoroughly dissolved, I add thereto in the usual way five parts, or about half of the weight of the pyroxylin, of the hydrochlorinated turpene or camphene. The compound may then be worked in the ordinary way to convert it intoa solid mass. I need not describe the mode of doing this, as it is well-known in the art. 1
I may also combine my new solvent with the nitrocellulose or pyroxylin by what is known as the dry process. In so doing I employ ten parts of pyroxylin to about half that weight of camphene or hydrochlorinated turpene. This is done by mixing the'bodies while in a ground state and then subjecting them to heat and pressure, whereby the turpene chlorid or camphene becomes a solvent without the aid of a liquid menstruum.
It will be understood by those skilled in the art that the hydrochlorinated turpene or the camphene may first be dissolved by any suitable solventas, for instance, the ethyl alcohol and ether above mentioned--and the nitrocellulose then added and that any of the known solvents for nitrocellulose or camphor may be employed. In fact my newly-discovered solvent may be employed as a substitute for camphor in any of the known ways of using camphor for nitrocellulose, and the hydrochlorinated turpene and camphene may be mixed together and used as a solvent.
I'have not found it necessary to add gumcamphor to aid the action of my newly-discovered solvent; but the addition of the same, if one chooses to add it, does not harm the product or interfere with the action of my solvent.
Iclaim- 1. The process of manufacturing pyroxylin compounds consisting of combining with nitrocellulose, a solvent consisting of the crystalline product produced by passing hydrochloric-acid gas through turpentine, substantially as set forth.
2. The process of manufacturing pyroxylin compounds consisting of combining with nitrocellulose the hydrochlorinated turpene (O I-I HOl) or camphene (C H as a solvent, substantially as set forth.
3. The process of manufacturing pyroxylin compounds consisting of combining with nitrocellulose hydorchlorinated turpene (G H H01) or camphene (C H as a solvent in connection with a liquid menstruum, substantially as set forth.
This specification signed and witnessed this 1st day of February, 1896.
OSKAR NAGEL.
