Description

Przedmiotem wynalazku jest sposób wytwarza¬ nia srodka impregnujacego do skór, zawierajacego mieszanine etylenoamidów kwasów tluszczowych z. a lub p monoglicerydami i niewielkimi iloscia¬ mi dwuglicerydów oraz kwasów tluszczowych.Znane srodki impregnujace charakteryzuja sie duzym udzialem monoglicerydów w stosunku do etylenoamidów. Zawartosc monoglicerydów powin¬ na byc wieksza niz 50% w odniesieniu do substan¬ cji aktywnej. Srodki tego typu otrzymuje sie w procesie dwuetapowym. Poczatkowo w reakcji ami- • nolizy glicerydów kwasów tluszczowych otrzymu¬ je sie mieszanine etylenoamidów i monoglicerydów kwasów tluszczowych o skladzie okolo 40% mono¬ glicerydów i okolo 60% etylenoamidów kwasów tluszczowych i dwuglicerydów.Celem uzyskania wlasciwego skladu srodków, mieszanine te wzbogaca sie monoglicerydami, otrzymanymi w reakcji glicerolizy glicerydów kwa- 20 sów tluszczowych, przebiegajacej w temperaturze 200^220°C. Tak otrzymana mieszanine standary¬ zuje sie kwasem olejowym i rozpuszcza w alkoho¬ lach np. etylowym, metylowym lub izopropylowym.Znane metody otrzymywania srodków impregnu¬ jacych wymagaja stosowania wysokich tempera¬ tur, przy czym uzyskuje sie niskie wydajnosci pro¬ cesu w etapie glicerolizy, nie przekraczajace 40%.Nieoczekiwanie stwierdzono, ze w jednoczesnej 30 reakcji aminolizy i glicerolizy glicerydów kwasów tluszczowych otrzymuje sie wysoka przemiane trójglicerydów na monoglicerydy, przy prowadze¬ niu procesu w nizszych temperaturach 140—160°C.Proces, prowadzony sposobem wedlug wynalazku, umozliwia otrzymanie w jednym procesie produ¬ ktu o zawartosci monoglicerydów powyzej 50% w stosunku do substancji aktywnej. Otrzymana w powyzszy sposób mieszanine, standaryzowana kwa¬ sem olejowym, rozpuszcza sie w alkoholach na przyklad: ' izopropylowym, etylowym lub metylo¬ wym i stosuje do impregnacji skór.Sposób prowadzenia procesu wedlug wynalazku pozwala uzyskac wyzsza wydajnosc procesu, zwla¬ szcza w odniesieniu do glicerolizy. Ponadto osiaga sie skrócenie czasu przebiegu reakcji przy zasto¬ sowaniu nizszych temperatur.Przyklad. Do 316 czesci wagowych surowego oleju rzepakowego dodaje sie 14 czesci wagowych dwuetylenotrójaminy i 40 czesci wagowych glice¬ ryny, mieszanine ogrzewa sie w ciagu czterech godzin w temperaturze 150°C, ochladza sie do 60°C.Do otrzymanej mieszaniny wlewa sie 37 czesci wa¬ gowych kwasu olejowego i 240 czesci wagowych izopropanolu. Otrzymuje sie 640 czesci wagowych srodka impregnujacego, zawierajacego okolo 60% substancji aktywnej, w której monoglicerydy sta¬ nowia okolo 70%. 99 00599 005 3 4 PLThe subject of the invention is a method of producing an impregnating agent for leather, containing a mixture of fatty acid ethyleneamides with a or p monoglycerides and small amounts of diglycerides and fatty acids. Known impregnating agents are characterized by a high proportion of monoglycerides in relation to ethyleneamides. The monoglyceride content should be greater than 50%, based on the active substance. These types of funds are obtained in a two-step process. Initially, the aminolysis reaction of fatty acid glycerides produces a mixture of ethyleneamides and monoglycerides of fatty acids with the composition of about 40% of monoglycerides and about 60% of fatty acid ethyleneamides and diglycerides. obtained by glycerolysis of fatty acid glycerides, proceeding at a temperature of 200-220 ° C. The mixture obtained in this way is standardized with oleic acid and dissolved in alcohols, e.g. ethyl, methyl or isopropyl alcohols. Known methods of obtaining impregnating agents require the use of high temperatures, and low efficiency of the process in the glycerolysis stage is obtained, not exceeding 40%. It was unexpectedly found that in the simultaneous reaction of aminolysis and glycerolysis of glycerides of fatty acids, a high conversion of triglycerides into monoglycerides is obtained, while carrying out the process at lower temperatures of 140-160 ° C. The process according to the invention makes it possible to obtain in one production process with a monoglyceride content greater than 50% of the active ingredient. The mixture obtained in this way, standardized with oleic acid, is dissolved in alcohols, for example: isopropyl, ethyl or methyl, and used for impregnation of leather. The method of carrying out the process according to the invention allows to obtain higher process efficiency, especially with regard to glycerolysis. Furthermore, a reduction in reaction times is achieved when lower temperatures are used. To 316 parts by weight of crude rapeseed oil, 14 parts by weight of diethylene triamine and 40 parts by weight of glycerol are added, the mixture is heated for four hours at 150 ° C, cooled to 60 ° C. 37 parts of water are poured into the mixture obtained. oleic acid and 240 parts by weight isopropanol. 640 parts by weight of an impregnating agent are obtained, containing about 60% of active substance, of which monoglycerides make up about 70%. 99 00 599 005 3 4 GB
