Description
Большое распространение в качестве клеющих материа; ов имеют, как известно, белки, получаемые, например, вываркой костей, кожи, а также в виде крови животных в консервированном или сухом виде (альбумин) или в виде казеина из молока и т. д. Кроме животных белков , наход т применение также и растительные белки. Большинство этих белков растворимо в воде и примен етс в водных растворах. При выварке костей или кожи получаютс довольно разбавленные растворы (бульоны), которые необходимо выпаривать, с целью получени кле , до высокой концентрации . Это св зано с расходом топлива и снижением качества кле .Large spread as adhesive materials; s are, as is well known, proteins obtained, for example, by evaporation of bones, skin, and also in the form of animal blood in canned or dry form (albumin) or in the form of casein from milk, etc. In addition to animal proteins, there are also and vegetable proteins. Most of these proteins are soluble in water and are used in aqueous solutions. By drying out bones or skin, rather dilute solutions (broths) are obtained, which must be evaporated, in order to obtain glue, to a high concentration. This is associated with fuel consumption and lower adhesive quality.
Предлагаемый способ получени клеющих веществ состоит в том, что водные растворы белков осаждают алкилнафталинсульфокислотой , полученный осадок промывают водой, а затем его расплавл ют.The proposed method for producing adhesives is that the aqueous solutions of the proteins precipitate with alkyl naphthalene sulfonic acid, the precipitate is washed with water, and then it is melted.
Вместо алкилнафталинсульфокислоты можно примен ть её соли с добавкой какой-либо минеральЕОй кислоты, лучше всего серной.Instead of alkylnaphthalenesulfonic acid, its salts can be used with the addition of a mineral EO acid, preferably sulfuric acid.
Пример 1. К 100 ч. раствора белка. полученного вываркой костей пли кожи, добавл ют на холоду при посто нном перемешивании 3--5% алкинафталинсульфокислоты , по отношению к белку, содержащемус в растворе.Example 1. To 100 hours protein solution. obtained by boiling out the bones of the skin or skin, add 3--5% alkyne-naphthalene sulfonic acid, with constant stirring, relative to the protein contained in the solution.
Из раствора выпадает хлопьевидный осадок. Дав отсто тьс последнему , с него сливают жидкость и промывают осадок холодной водой 2-3 раза, или же в начале осадок нагревают до 50 - 60 (дл ускорени отделени воды), с него вновь сливают выделившуюс жидкость и только после этого перенос т осадок в тару.A flocculent precipitate falls out of solution. After allowing to settle last, the liquid is drained from it and the precipitate is washed with cold water 2-3 times, or at the beginning the precipitate is heated to 50-60 (to accelerate the separation of water), the separated liquid is again drained and only after that the precipitate is transferred to tara
Пример 2. К 100 ч. раствора белка на холоду добавл ют 5-8% соли алкилнафталинсульфокислоты, по отношению к белку. При употреблении водных растворов реактива делаетс соответствующий расчёт количества его, необходимого дл осаждени . После энергичного перемешивани в масс} добавл ют струей при размешивании 10-процентный раствор серной кислоты до тех пор, пока не перестанет выпадать осадок, дл чего бывает достаточно 2-3%, по отношению к белку, 100-процентнои серной кислоты. № 64311 Обработка осадка производитс по вышеописанному. Продукт может быть высушен, причём на сушку его расходуетс немного тепла. Предмет изобретени 1. Способ получени клёющих веш,еств из водных растворов белков , отличающийс тем, что водные растворы белков осаждают алкилнафталинсульфокислотой, полученный осадок промывают, после чего его расплавл ют, 2. Видоизменение способа по п. 1, отличающеес тем, что вме алкилнафталинсульфокислоты примен ют ее соли с добавкой какой-либо минеральной кислоты, например серной.Example 2. To 100 parts of a cold protein solution, 5-8% of an alkyl naphthalene sulfonic acid salt are added, relative to the protein. When using aqueous solutions of the reagent, an appropriate calculation is made of the quantity required for precipitation. After vigorous stirring in the masses, a 10% solution of sulfuric acid is added by a stream while stirring until the precipitate ceases to fall, for which 2-3% is sufficient, relative to protein, 100% sulfuric acid. No. 64311 Sludge is treated as described above. The product can be dried, and a little heat is used to dry it. Subject of the invention 1. A method for producing agglomerates from aqueous solutions of proteins, characterized in that aqueous solutions of proteins are precipitated by alkylnaphthalenesulfonic acid, the precipitate is washed, after which it is melted 2. A method modified according to claim 1, characterized in that its salts are used with the addition of any mineral acid, for example sulfuric.
