Description

Przedmiotem wynalazku jest sposób wytwarzania srod¬ ka antyelektrostatycznego do stosowania w przerobiewló¬ kien syntetycznych, zwlaszcza poliakrylonitrylowych be¬ dacego produktem reakcji siarczanu dwumetylu i trójeta- noloaminy.The subject of the invention is a method of producing antistatic cassette for use in processing synthetic foams, especially polyacrylonitrile bees to give the reaction product of dimethyl sulphate and triethyl noloamines.

Dzialajac bezposrednio siarczanem dwumetyluna tróje- tanoloamine otrzymuje sie produkt o dobrych wlasnos¬ ciach antyelektrostatycznych, który jednak ze wzgledu na brunatna barwe nie moze byc stosowany do preparacji antyelektrostatycznej wlókien bialych lub barwionych na jasne kolory z powodu przyszarzenia ich bielilub odcienia.Acting directly triethyl dimethyl sulphate tanolamine gives a product with good properties anti-electrostatic cuts, which, however, due to brown color can not be used for preparation antistatic fiber, white or dyed on light colors due to graying of their whiteness or shade.

W celu usuniecia szkodliwego zabarwienia stosuje sie sposoby chemiczne jak (bielace srodki utleniajace lub redukujace) lub metody fizyczne takie jak absorpcja na weglu aktywowanym, zelu krzemionkowym itp. Odbar¬ wienie produktu stwarza koniecznosc zastosowania do¬ datkowegoprocesu, wymagajacegoodpowiedniej aparatu¬ ry, przy czym sposoby fizyczne i chemiczne sa nie zawsze skuteczne i zaleza od skladu i ilosci barwnych zanieczysz¬ czen.In order to remove harmful color, it is used chemical methods such as (bleaching oxidants or reducing) or physical methods such as absorption on activated carbon, silica gel, etc. Decolorizing The addition of the product necessitates the application of an additional process that requires the appropriate apparatus ry, where physical and chemical methods are not always effective and depends on the composition and amount of colored impurities red.

Celem wynalazku jest opracowanie sposobu otrzymania bezbarwnego srodka antyelektrostatycznego bedacego produktem reakcji siarczanu dwumetylu i trójetanoloami- ny z pominieciem dodatkowej operacji odbarwienia.The object of the invention is to develop a method of obtaining colorless antistatic agent being the reaction product of dimethyl sulphate and triethanolamine ny without the additional decolorization operation.

Istota wynalazku polega na prowadzeniu reakcji siar¬ czanu dwumetylu z trójetanoloamina w obecnosci siarczy¬ nów metali alkalicznych lub ziem alkalicznych w ilosci -10 g/l kg trójetanoloaminy, które powoduja powstanie ukladu eliminujacego mozliwosc powstania ubocznych substancji barwnych, tworzacych sie podczas ogólnie przyjetych sposobów prowadzenia reakcji metylacji tróje¬ tanoloaminy siarczanem dwumetylu. Otrzymany sposo¬ bem wedlugwynalazku srodek odznacza siedobrymi wlas¬ nosciami antyelektrostatycznymi obniza opornosc powie- rzchniowa wlasciwa wlókna poliakrylonitrylowego do 10H-10"Q jest bezwonny i trwale bezbarwny.The essence of the invention consists in carrying out the sulfur reaction dimethylate with triethanolamine in the presence of sulfite new alkali metals or alkaline earth metals in quantity -10 g / l kg of triethanolamine which is formed a system that eliminates the possibility of side effects color substances that form during general the methods adopted for carrying out the triethylation reaction tanolamine with dimethyl sulfate. The obtained method because, according to the invention, the agent is distinguished by its own properties antistatic materials reduces air resistance a suitable polyacrylonitrile fiber for 10H-10 "Q is odorless and permanently colorless.

Przyklad. Rozpuszcza sie 1,05 czesci wagowych sied- miowodnego siarczynu sodowego w 2,05 czesciach wago¬ wych wody o temperaturze okolo 40°. Do 53,0 czesci wago¬ wych trójetanoloaminy wprowadza sie roztwór siarczynu sodowego i miesza. Do otrzymanej mieszaniny, przy cia¬ glym mieszaniu, dodaje sie powoli 43,9 czesci wagowych siarczanu dwumetylu, utrzymujac temperature 40-50°C.Example. 1.05 parts by weight of the seven sodium hydrogen sulphite in 2.05 parts by weight water at a temperature of around 40 °. Up to 53.0 parts by weight The sulphite solution is introduced into triethanolamine soda and mixed. To the mixture obtained, while While stirring, 43.9 parts by weight are slowly added dimethyl sulphate, maintaining a temperature of 40-50 ° C.

Nastepnie mieszanine reakcyjna ogrzewa sie do tempera¬ tury 90° i utrzymuje w tej temperaturze w ciagu 0,5 godzi¬ ny. Otrzymuje sie produkt ciekly bezbarwny (<]1 mg J2) 100 ml roztworu wedlug skali jodowej. Naniesionyz kapie¬ li wodnej o stezeniu 10 g/l obniza opornosc powierzchnio¬ wa wlasciwa wlókna poliakrylonitrylowego do 108-10BQ.The reaction mixture is then warmed to room temperature temperature 90 ° and kept at this temperature for 0.5 hours ny. A colorless liquid product is obtained (<] 1 mg J2) 100 ml of solution according to the iodine scale. Drip-in 10 g / l of water lowers the surface resistance appropriate polyacrylonitrile fiber to 108-10BQ.
