Making use of woollen cleaning sewage as basic material
Preparation of crude Lanolin Oil Include aluminum trichloride to the wool scouring sewer to get lanolin-containing mud, and absorb water to get mud. Take 600kg of sludge, add 480kg of benzene, stir while adding, warmth at 56 ° C for 1 hr, quit stirring, and choose 1 hr. After explanation, the benzene liquid liquifies 6% -40% of lanolin, moves it right into a purification tower, and also heats up and also distills up until the lanolin material gets to 34%, cool to below 40 ° C and also release to acquire the crude item of Lanolin Oil.
Wool cleaning sewage [AlCl3] → sludge [benzene, 30 ° C] → crude lanolin
Prep Work of Neutralized Phenyl Fat Take 2100kg of lanolin unrefined item right into the response pot, heat to 50 ° C, after that include hot about 50% (g/g) sulfuric acid remedy into the lanolin crude item, stir for 45min, go for half an hour, release the offal, Include light ethanol to the phenyl material layer, include water, heat as well as keep at 60 ° C, mix for half an hour, settle for half an hour, launch the scraps, as well as acquire acid-treated phenyl material. Take acid-treated phenyl fat as well as add 180kg of ethanol, gradually include concerning 70kg of 300g/L sodium hydroxide remedy, adjust the pH to 9, add 180kg of water, keep cozy at 60 ° C, mix continually from the addition of ethanol to the conclusion of including water, continue to mix for 10min, and allow it stand, Precipitate for 1h, release the scraps, include light ethanol to the phenyl ester layer, mix, precipitate for 1h, launch the scraps, as well as reduce the effects of the phenyl esters.
Unrefined lanolin [sulfuric acid, water] → [light ethanol] acid treatment of phenyl ester [60 ° C, ethanol] → [NaOH, WATER] reduced the effects of phenyl ester
Prep work of finished product of medicinal Lanolin Oil Take neutralized phenyl ester, add 24kg of 3.8% hydrogen peroxide, mix, keep warm at 60 ° C, opt for 35min, launch offcuts, maintain pH 8-9, add light ethanol, settle for 2h, release offcuts, and also get refined Phenyl ester. Distillation, fluid temperature level 110 ℃ vacuum dissipation up until no evaporation, cooling down to 60 ℃, include ethanol, stir, speed up for 1 hour, separate the reduced lanolin, add ethanol, warm and mix for 10 minutes, discard the ethanol, evaporate the ethanol under decreased stress, Filtrate with silk cloth to get medicinal lanolin completed item.
Counteracted phenyl ester [H2O2, ethanol, 60 ° C] → fine-tuned phenyl ester [ethanol, 110 ° C] → completed product of Lanolin Oil.
