COMPOSITION OF MATTER AND PROOESS OF MAKING THE SAME.
No Drawing.
To all whom it may concern:
Be it known. that I, I-IEnBnR'r S. LEVENSON, a citizen of the United States, and a resident of New York city, borough of Brooklyn, State of New York, have invented new and useful Improvements in Composition of Matter and Processes of Making the Same, of which the following is a specification.
This invention relates to the product-ion of a composition of matter having adhesive properties, and more particularly such a composition which can be used as a binder for granular or pulverulent materials,"as for example, in the production of briquets, the treatment of road surfaces, and the like.
The objects of theinvention are to secure such a'binder which shallbe insoluble by water and moisture under usual working conditions, and thus to secure'a perfect and complete binding action; to enable an ingredient soluble in water to be used in the production of such a binder and yet have the binder insoluble; to thus enable concentrated sulfite liquor to be advantageously used in the production of such a binder;.to produce such a binder from concentrated sulfite liquor and fatty oil pitch; to unite said concentrated sulfite liquor and fatty oil pitch so that they StOIGd OIFShIPPGd, but will always be ready for use, and to obtain other advantages and results. 1
- In the manufacture of paper pulp by the.
sulfite method, wood is heated in a digester with an aqueous solution of bi-sulfite of lime (calcium acid sulfite). Sometimes dolomitic or ma esian lime is used in 'making the sulfite iquor, in which case it contains acid sulfite of'magnesia. In the digester about half of the wood goesinto the solution, forming sulfite waste liquor,-th'e remainder forming paper pulp. In going into solution the organic material of the wood, and particularly what is known as the lignin complex, forms new combinations with the sulfurous radical and the bases present. For the sake of a name, the new bodies formed are usually called ligno-sulfonat es. There are small amounts of sugars and other bodies present, but the characteristic organic substances of the sulfite waste liquor are these ligno-sulfonates. The ligno-suL fonates have the ch'aracterof salts of sulfonic acids and the salts formed with most or all of the bases are soluble.
will not separate, as when Application filed February 17, 1921. Serial No. 445,748.
, Sulfite waste liquor with proper care in manipulation may be evaporated down to thick liquids or dry compositions, sometimes known as sulfite pitchesa These concentrated products have found an extensive market in the country for various purposes, but mainly as adhesives, such as making sand cores and briquets. Their adhesive propertlesare very good indeed; they may be used in agglutinating any pulverulent material; But since the ligno-sulfonates are soluble bodies, in many of these uses, and particularly where the agglutinated material is to be exposed to the weather, the solubihty of the binder is an inconvenience. Many efforts have been made to obviate this by incorporating other binders with the sulfite waste liquor preparations without much success.
I have found that these diiiiculties may be obviated and a binder secured which shall be free from them by mixing fatty oil pitch withthe concentrated sulfite liquor. and I use the term fatty oil pitch as opposed to natural pitches and designating the still residue left after free fatty acids are steam distilled from cottonseed oil, palm oil, wool fat, grease, etc. The fatty oil pitches contain olein, palmitin and stearin, and some of them would be covered by the term stearine pitch. The fatty oil itch known 'in the trade as fvegetable itc containing prin cipally 'ol'ein and pa mitin, is well suited to m purpose, and I use that, though I do not wish to be restricted to it. A smaller quantity of fatty oil itch than of sulfite liquor is best employed and the two i edients must be thoroughly mixed, as by stirring or other agitating; if this is done in the presence of heat it is advantageous, and so it is convenient to first dilute the concentrated sulfite liquor with hot water and then add the fatty oil pitch. Preferably, I take four (4) parts by weifight' of commercial 30 B. concentrated slu te'liquor and re-vdilute it with hot water at 160 F.; to this I add one (1) part of commercial vegetable pitch, stirring it in well. The hot water may however, be at any temperature from 120 F. to boiling point, and the proportions stated may be varied by one skilled in the arts to which this invention relates, without departing from the spirit and scope of the invention, and I do not wish to be understood as limiting myself except as required by the following claims when construed in the light of the prior art.
in a dry state of approximately two to one,
that is, if concentrated sulfite liquor of about 65% solids instead of 50% is used, the proportions would be only three of the concentrated sulfiteliquor to one of vege' table pitchin order to maintain the above proportions. The water in the binder is only used as a vehicle to make it liquid and aid in the distribution in the pulverulent material. 7
' The preparation made as described may he stored, shipped and used without separation of the components, and it may be used as a binder for any granular orpulverulent materials, being capable of making really waterproof briquets and of being used to great advantage in road dressings, core compounds for waterproofing cements and for all similar uses.
It should be noted that the water wlth which I dilute the concentrated sulfite llquor, before adding the vegetable pitch, is asolvent of both said ingredients, or a co-solvent, and this is an important feature in making in binder. Any co-solvent of concentrated su' fite liquor and the fatty oil pitch can be used, for example, carbon tetrachloride, carbon bisulphide or ordinary benzol diluted, for stearin base itches, and I do not )WlSll I to be limited int lat respect.
