Abstract
Przedmiotem zgłoszenia jest nowatorski 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% - 95% (m/m) metyloetyloketonu i odpowiednio 90% - 5% (m/m) eteru metylo-tert-butylowego, 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 0,08 — 10,0°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 1,9:1 do 12,0:1 (m/m), przy czym wielkość każdego jednostkowego rozcieńczenia wyrażona stosunkiem masowym rozpuszczalnika do surowca wynosi od 0,1:1 do 5,8:1 (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 6,0:1 (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 41°C, oraz następnie z osadu oddestylowuje się rozpuszczalnik uzyskując wosk utwardzony o podwyższonej temperaturze krzepnięcia od 6 do 14°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 an innovative method of producing modified lanolin and hardened wax, which method consists in lanolin being the raw material, characterized by a solidification point of approx. residual 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% - 95% (m/m) methyl ethyl ketone and 90% - 5% (m/m) methyl tert-ether, respectively mixture of raw material and solvent, which is then cooled at a controlled rate, with simultaneous supply of chilled solvent in 1-6 portions of further dilution at a cooling rate in the range of 0.08 - 10.0°C/min, until reaching a temperature of -10 to -30°C, where the ratio of the total amount of solvent from dilutions and washings to the raw material is in the range of 1.9:1 to 12.0:1 (m/m), with the size of each unit dilution expressed as a ratio solvent to the raw material is from 0.1:1 to 5.8:1 (m/m), then in the temperature range from -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 the crystallization step, used in the amount of 0.1:1 to 6.0:1 (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 modified lanolin with a reduced congealing point of 35 to 41°C, and then the solvent is distilled from the precipitate to obtain hardened wax with an increased congealing point of 6 to 14°C in relation to these temperatures before subjecting the raw material, lanolin, to the process of solvent separation into filtrate and precipitate and distillation of the solvent from them.
