How many pounds of wool do I need to extract 1 kg of lanolin? High bounty

Synthesis method.

Preparation of lanolin crude products with washing sewage as raw materials Aluminum chloride is added to washing sewage to obtain a slurry containing lanolin, which absorbs water and obtains sludge. Take 600kg of sludge, add 480kg of benzene, stir while adding, heat 56 keep warm for 1h, stop stirring, precipitate for 1h, dissolve lanolin 6%-40% in benzene solution after clarification, move it into the distillation tower, heat and distill until it contains 34% lanolin, cool down to below 40 and release it to obtain crude lanolin. Preparation of crude lanolin neutralization of lanolin [ALCL3] sludge [benzene, 30] Take 2100kg of crude lanolin and put it into the reaction pot, heat it to 50, and then add about 50% (g g) sulfuric acid solution to the crude lanolin product, stir for 45min, precipitate for half an hour, release the lower foot, add light ethanol to the benzene lipid layer, add water, heat and keep warm 60, stir for half an hour, precipitate for half an hour, release the lower foot, and obtain acid to treat benzene fat.

Take acid to treat benzene fat and add 180kg of ethanol, gradually add 300g l sodium hydroxide solution about 70kg, adjust pH9, add 180kg of water, keep warm 60, stir continuously from adding ethanol to the end of adding water, and then continue to stir for 10min, stand still, precipitate for 1h, release the lower foot, add light ethanol to the benzene lipid layer, stir, precipitate for 1h, release the lower foot, and neutralize the benzene lipid.

Preparation of crude lanolin [sulfuric acid, water] [light ethanol] acid treatment of benzene lipid [60, ethanol] [NaOH, H2O] neutralization of benzene lipid medicinal lanolin finished products Take neutralized benzene resin, add 24kg of hydrogen peroxide, stir, keep warm for 60, precipitate for 35min, release the lower foot, keep pH 8-9, add light ethanol, precipitate for 2h, release the lower foot, and obtain refined benzene fat. Distillation, liquid temperature 110 vacuum evaporation until evaporation, cooling to 60, add ethanol, stirring, precipitation for 1h, separate the lower lanolin, add ethanol, heat and stir for 10min, discard ethanol, divaporate ethanol under reduced pressure, filter silk cloth to obtain medicinal lanolin. Neutralized benzene lipid [H2O2, ethanol, 60] refined benzene lipid [ethanol, 110] lanolin finished product.

If you go to the entry, it's not made of wool, it's made of wool, it's washed wool sewage as raw materials, and it's too luxurious to make it with wool!

Let's start by looking at how much lanolin there is in a kilogram of wool.

10 catties of sheep dismantling coarse wool contains 1 catty of wool fat. By analogy, 100 catties contain 40 catties of wool fat.

Lanolin is a kind of secreted oil attached to wool, the main components are esters formed by steroids, fatty alcohols and triterpene alcohols and about the same amount of fatty acids, accounting for about 95% of the town, and also contains 4% of free alcohols, and a small amount of free fatty acids and hydrocarbons.

100 catties of wool limb type if the country is short of hungry wool, it contains about 30 grams of wool fuwan fat, if Australian merino wool, it will be higher, can reach about 45 grams.

Take 100 kg of weight fat medium to upper breeding ewes as an example, every day need to eat a pound of dry matter amount of feed, of which concentrate feed can be fed catty, the fetal growth rate in the late pregnancy can be increased appropriately to increase the amount of concentrate feed, but it should not exceed catty, the remaining 3 catties of ulnar infiltration resistance is forage; Taking 50 kg of fattening sheep as an example, it is necessary to eat a pound of dry matter feed every day, of which concentrate can account for about 30% of the catty, and the amount of forage feed is catty.

However, a considerable amount of forage moisture content is larger, can reach about 70%, that is to say, 1 kg of fresh forage only has a kg of dry matter, ewes need 10 kg of fresh forage in the case of 3 kg of dry matter forage a day, and 4 kg of fresh forage is needed in the case of fattening sheep a day of dry matter forage.
