Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania zmodyfikowanej lanoliny i wosku utwardzonego, który to sposób polega na tym, że będącą surowcem lanolinę, charakteryzującą się temperaturą krzepnięcia ok. 42°C poddaje się procesowi rozdzielania rozpuszczalnikowego na filtrat - roztwór zmodyfikowanej lanoliny i osad - wosk utwardzony zawierający pozostałości rozpuszczalnika, obejmującemu etap krystalizacji i etap filtracji, przy czym w etapie krystalizacji surowiec poddaje się pierwszemu rozcieńczeniu rozpuszczalnikiem zawierającym 10% - 90% (m/m) metyloetyloketonu i odpowiednio 90% - 10% (m/m) toluenu, uzyskując mieszaninę surowca i rozpuszczalnika, którą następnie oziębia się z kontrolowaną prędkością, z równoczesnym doprowadzeniem oziębionego rozpuszczalnika w 1-6 porcjach kolejnego rozcieńczenia przy szybkości schładzania w zakresie 0,15 - 6,0°C/min, aż do osiągnięcia temperatury od -10 do -30°C, przy czym stosunek sumarycznej ilości rozpuszczalnika z rozcieńczeń i przemywania do surowca zawiera się w przedziale od 1,8:1 do 9,0:1 (m/m), przy czym wielkość każdego jednostkowego rozcieńczenia wyrażona stosunkiem masowym rozpuszczalnika do surowca wynosi od 0,2:1 do 3,8:1 (m/m), po czym w zakresie temperatur od -10 do -30°C, odfiltrowuje się wydzielony osad, który przemywa się zimnym rozpuszczalnikiem o takim samym składzie jak rozpuszczalnik używany w etapie krystalizacji, stosowanym w ilości od 0,1:1 do 3,0:1 (m/m), wyrażonej stosunkiem masowym rozpuszczalnika do surowca, a następnie z roztworu filtratu oddestylowuje się rozpuszczalnik uzyskując produkt końcowy, którym jest zmodyfikowana lanolina o obniżonej temperaturze krzepnięcia od 35 do 36°C, oraz następnie z osadu oddestylowuje się rozpuszczalnik uzyskując wosk utwardzony o podwyższonej temperaturze krzepnięcia od 6 do 19°C w stosunku do wartości tych temperatur przed poddaniem surowca lanoliny procesowi rozdzielania rozpuszczalnikowego na filtrat i osad oraz oddestylowanie z nich rozpuszczalnika.The subject of the application is a method of producing modified lanolin and hardened wax, which method consists in lanolin being the raw material, characterized by a solidification point of about 42°C, being subjected to a solvent separation process into a filtrate - modified lanolin solution and precipitate - hardened wax containing residues a solvent, comprising a crystallization step and a filtration step, wherein in the crystallization step, the raw material is subjected to a first dilution with a solvent containing 10% - 90% (w/w) methyl ethyl ketone and 90% - 10% (w/w) toluene, respectively, to obtain a mixture of the raw material and of solvent, which is then cooled at a controlled rate, with simultaneous addition of chilled solvent in 1-6 portions of a further dilution at a cooling rate in the range of 0.15 - 6.0°C/min until a temperature of -10 to -30°C is reached C, where the ratio of the total amount of solvent from dilutions and washing to the raw material ranges from 1.8:1 to 9.0:1 (m/m), where the size of each unit dilution expressed as the mass ratio of the solvent to the raw material is from 0.2:1 to 3.8:1 (m/m), after which, at a temperature range of -10 to -30°C, the separated precipitate is filtered off, which is washed with a cold solvent of the same composition as the solvent used in step crystallization, used in the amount from 0.1:1 to 3.0:1 (m/m), expressed as the mass ratio of the solvent to the raw material, and then the solvent is distilled from the filtrate solution to obtain the final product, which is a modified lanolin with a reduced freezing point from 35 to 36°C, and then the solvent is distilled from the precipitate to obtain a hardened wax with an increased congealing point of 6 to 19°C in relation to the values of these temperatures before subjecting the lanolin raw material to the process of solvent separation into filtrate and precipitate and distilling the solvent from them.
