Abstract

Przedmiotem zgłoszenia jest sposób otrzymywania zmodyfikowanego oleju jojoba i utwardzonego wosku roślinnego, w którym to sposobie będący surowcem olej jojoba, charakteryzujący się temperaturą mętnienia ok. 9°C, temperaturą płynięcia ok. 8°C i temperaturą krzepnięcia ok. 7°C poddaje się procesowi rozdzielania rozpuszczalnikowego na filtrat - roztwór zmodyfikowanego oleju jojoba i osad - wosk utwardzony zawierający pozostałości rozpuszczalnika, obejmującemu etap krystalizacji i etap filtracji, przy czym w etapie krystalizacji surowiec poddaje się pierwszemu rozcieńczeniu rozpuszczalnikiem 1,2-dichloropropanem, 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 0,14 — 7,6°C/min, aż do osiągnięcia temperatury od -16 do -30°C, przy czym stosunek sumarycznej ilości rozpuszczalnika z rozcieńczeń i przemywania do surowca zawiera się w przedziale od 2,41 do 11,2:1 (m/m), przy czym wielkość każdego jednostkowego rozcieńczenia wyrażona stosunkiem masowym rozpuszczalnika do surowca wynosi od 0,45:1 do 5,0:1 (m/m), po czym w zakresie temperatur od -16 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 0,4:1 do 4,9:1 (m/m), wyrażonej stosunkiem masowym rozpuszczalnika do surowca, a następnie z filtratu oddestylowuje się rozpuszczalnik uzyskując produkt końcowy, którym jest zmodyfikowany olej jojoba o obniżonych: temperaturze mętnienia od 8 do 11°C temperaturze płynięcia od 8 do 12°C i temperaturze krzepnięcia od 8 do 12°C, oraz następnie z osadu oddestylowuje się rozpuszczalnik uzyskując wosk utwardzony o podwyższonych: temperaturze mętnienia od 2 do 7°C, temperaturze płynięcia od 1 do 5°C i temperaturze krzepnięcia od 1 do 4°C w stosunku do wartości tych temperatur przed poddaniem surowca, oleju jojoba procesowi rozdzielania rozpuszczalnikowego na filtrat i osad oraz oddestylowanie z nich rozpuszczalnika.The subject of the application is a method of obtaining modified jojoba oil and hardened vegetable wax, in which the jojoba oil being the raw material, characterized by a cloud point of about 9°C, a pour point of about 8°C and a solidification point of about 7°C, is subjected to a process solvent separation into filtrate - modified jojoba oil solution and precipitate - hardened wax containing solvent residues, comprising a crystallization step and a filtration step, wherein in the crystallization step, the raw material is first diluted with 1,2-dichloropropane solvent, obtaining a mixture of raw material and solvent, which is then is cooled at a controlled rate, with simultaneous supply of chilled solvent in 1-6 portions of sequential dilution, at a cooling rate in the range of 0.14 - 7.6°C/min, until a temperature of -16 to -30°C is reached, with where the ratio of the total amount of solvent from dilutions and washing to the raw material ranges from 2.41 to 11.2:1 (m/m), where the size of each unit dilution expressed as the mass ratio of solvent to raw material is from 0.45:1 to 5.0:1 (m/m), then in the temperature range from -16 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 an amount from 0.4:1 to 4.9:1 (m/m), expressed as the mass ratio of the solvent to the raw material, and then the solvent is distilled from the filtrate to obtain the final product, which is a modified jojoba oil with reduced: cloud point from 8 to 11 °C, pour point from 8 to 12°C and solidification point from 8 to 12°C, and then the solvent is distilled from the precipitate to obtain hardened wax with increased: cloud point from 2 to 7°C, pour point from 1 to 5°C and freezing point from 1 to 4°C in relation to the values of these temperatures before subjecting the raw material, jojoba oil, to the process of solvent separation into filtrate and precipitate and distillation of the solvent from them.
