Description

Lugi siarczynowe blonnika znajduja wielostronne zastosowanie; uzywane sa np, jako klej, zaprawa, garbnik, srodek do zabezpieczania wlókien i do mycia. W tym celu lugi dostarczane sa na rynek w posta¬ ci zageszczonej do 30 — 35° Be o wlasno¬ sciach syropu, gdyz lug odparowany do sucha jest preparatem bardzo higroskcpij- nym i podczas przechowywania w miej¬ scach wilgotnych zestala sie na twarda ciemna mase zywicowa, której obróbka po¬ laczona jest ze znacznemi niedogodnoscia¬ mi. Przewóz lugów zawierajacych wode jest za kosztowny i uzycie ich w tej postaci polaczone jest z pewnemi trudnosciami.Obecnie z lugów siarczynowych blon¬ nika udalo sie otrzymac zapomoca susze¬ nia, zachowujac ich cenne wlasnosci, nie- rozplywajace sie cialo stale; w tym cela przed odparowywaniem lugów 'siarczyno¬ wych, które dobrze jest uwolnic od wapna i zelaza, usuwa sie lub unieszkodliwia skladniki wywiolujace ich higroskqpij- nosc.Te ostatnie mozna usunac z lugów, obrabiajac je srodkami, które chociaz osa¬ dzaja sulfoniany, lecz nie powoduja spie¬ kania sie i rozplywania lugów odparowa¬ nych do sucha, jak np. pewne cukry. Li- gninosulfoniany daja sie w ten sposóo 'od¬ dzielic i jako takie wysuszyc. Mozna rów¬ niez, przed odparowaniem zawarte w lu¬ gach ciala higroskopiijne rozlozyc, np. pewne cukry mozna poddac fermentacji lub tez mozna lugi obrobic srodkami utle¬ niaj acemi, gotowac z kwasami lub rozcien- ezonemi alkaljami lub wogóle obrobic je oddzialywaj acemi alkalicznie srodkami, stosGwanemi w nadmiarze i nastepnie zo¬ bojetnic kwasami, i w ten sposób osadzic wiekszosc rozpuszczonych skladników.Skladniki higroskopijne mozna równiezwydzieli z lugów aa/pomoca dijalizy. Nie¬ koniecznie jednak nalezy usuwac z lugów sklaicfniki hi^p^kqpi|ne, wystarczy je przed odparowaniem przeprowadzic w stan nie- hlgrogkopijny, np. zapomoca kondensacji z aldehydami, kwasami karbomowemi. zwiazkami ciksyarylawemi, jak np. fenola- mii i ich produktami np. kwasem salicylo¬ wym.Sposób wedlug wynalazku objasniaja ponizsze przyklady.Przyklad L Uwolnione od zelaza i wap¬ na 250 czesci lugów siarczynowych blon¬ nika o 30° Be ogrzewa sie w ciagju pewne¬ go czasu do temperatury lOO^ z 62 czescia¬ mi roztworu wodorotlenku sodowego o 38° Be, poczerni roztwór alkaliczny zobojetnia sie 50 czesciami! kwasu solnego 20° Be i, dodajac 40 czesci chlioriku sodowego, wy¬ dziela sie, ogrzewajac umiarkowanie, zada¬ na czesc skladowa lugów w stanie stalym.Osad sprasowany suszy sie najlepiej w prózni. W ten sposób otrzymuje sie cialo zólitobrujnatne, latwo rozpuszczalne w wo¬ dzie, które nawet po dluzsizem pozostawa¬ niu na powietrzu nie ulega zmianie.Przyklad II.

Nastepnie po dodaniu 61 cze¬ sci kwasu solnego o 20° Be i 50 czesci chlorku sodowego cedzi sie.Przyklad IIL Czesci 375 sianczyno¬ wych lugów blonnika, majacych okolo 30° Be laczy sie z 37 czesciami bezwodnego weglanu sodowego i ogrzewa w ciagu pew¬ nego czasu przy temperaturze wrzenia. Na¬ stepnie roztwór rozciencza sie nieznaczna iloscia wody, dolewa 77 czesci kwasu sol¬ nego o 20° Be i nastepnie osad wysala sie, Przyklad IV.

Otrzymany w ten sposób zólto- brunatny srodek daje sie z latwoscia sproszkowac.Przyjjtllaid V. Czesc 1 zgeszczonych do¬ czyszczonych lugów siarczynowych sklóca sie iz 2 czesciami alkoholu (denaturowanego), który dobrze jest dodawac stopniowo.

PL PLFiber sulphite lugs are used in many ways; They are used, for example, as glue, mortar, tanning agent, fiber preservative and washing agent. For this purpose, the slug is delivered to the market in a concentrated form to 30-35 ° Be with the properties of a syrup, because the slug evaporated to dryness is a very hygroscopic preparation and during storage in wet places it solidifies into a hard dark mass resin, the treatment of which is associated with considerable disadvantages. The transport of water-containing harnesses is too expensive and their use in this form is associated with certain difficulties. At present, the sulfite fiber of the fiber has been obtained without drying, preserving its valuable properties, non-flowing body permanently; including the cell before the evaporation of sulphite liquors, which is good to free from lime and iron, removes or neutralizes the ingredients causing their hygroscopic substances. The latter can be removed from the liquors by treating them with agents which, although they deposit sulfonates, but they do not cause the fracture and spreading of dry evaporated liquors, such as certain sugars. The lignin sulfonates can thus be separated and dried as such. It is also possible to decompose the hygroscopic bodies contained in the slug before evaporation, e.g. some sugars can be fermented or the slug can be treated with oxidizing agents, boiled with acids or diluted with alkalis, or treated in general with alkaline agents. , they are stacked in excess and then morbid with acids, thereby depositing most of the dissolved components. Hygroscopic components can also be separated from the aa liquors by dialysis. It is not necessary, however, to remove the high-acid condensers from the liquors, it is enough to make them non-halogenated before evaporation, for example by condensation with aldehydes, carbomic acids. with cixarylavemic compounds, such as phenolamia, and their products, e.g. with salicylic acid. The method according to the invention is illustrated by the following examples: Example L Freed from iron and calcium for 250 parts of sulphite strands of the fiber by 30 ° Be heated in a continuous some time to 100 ° C with 62 parts of a sodium hydroxide solution of 38 ° Be, the blackened alkaline solution becomes neutralized with 50 parts! Hydrochloric acid 20 ° Be and, adding 40 parts of sodium chloride, the desired part of the solids is released by heating moderately. The pressed sediment is dried preferably in a vacuum. In this way, a yellow-brittle body is obtained, easily soluble in water, which does not change even after being left in the air for a long time. Example II. Parts of 375 parts of sulfite fiber at 30 ° B are processed by heating with 83 parts of a hydroxide solution! potassium by 50 ° Be and with a small amount of water. Then, after adding 61 parts of hydrochloric acid at 20 ° Be and 50 parts of sodium chloride, it churns. Example IIL Parts of 375 haybone fiber strands, having about 30 ° Be combined with 37 parts of anhydrous sodium carbonate and heated for certain time at boiling point. Then the solution is diluted with a small amount of water, 77 parts of hydrochloric acid are added by 20 ° B and then the precipitate is sown, Example IV. The sulphite lugs of blonmLk are fermented in the manner used in the production of alcohol, the separated sediment is evaporated to dryness in a vacuum. The yellow-brown agent obtained in this way can easily be pulverized. Take tllaid V. Part 1 of the thickened cleaned sulfite slurries turns into 2 parts of alcohol (denatured), which is good to add gradually. After some time, a part of the rumps in the form of a dense mass settles on the bottom of the vessel. It is separated by decolorization from the alcoholic solution containing all the hygroscopic components. The flax sediment is then washed with alcohol, dried at a temperature of 90-10 ° C and pulverized. The alcohol is completely restored. Example VI. Parts of 300 sulphite fiber, containing about 30% dry solids, are boiled by adding 10 parts of hydrochloric acid, with 47 parts of phenol over time, and the resulting solution is evaporated to dryness. 0- sticks to the presses of nfehignocopyin, it is soluble.
