Glycerine
Glycerine, chemically called glycerol, is a sweet tasting, colorless, odorless, and viscous liquid. It is naturally occuring as the backbone of all triglycerides, and is most commonly produced as a biproduct of soap or biofuel in the reaction depicted below. The production of soap is the same process without methanol.
How to make: glycerol aka glycerine can be gained through vegetable oil to make glycerol you will need to 200ml of methanol and 9g of sodium hydroxide and mix then heat 800ml vegetable oil to 50 degrees Celsius then mix with the methanol and sodium hydroxide mixture then mix for approx. 30minutes leave to settle for 1 hour minimum the mixture should spit into two layers a dark layer at the bottom (mostly glycerol) and an upper layer of mostly bio-diesel you can just pour this biodiesel into another container (there may be chunks this is fine it is biodiesel as well) the the mostly glycerol layer can be poured out into another container the let settle the pick out the biodiesel chunks should now look like the picture to the left now you have crude glycerine now add 17ml of 31.45%HCI mix then the reaction will cause water to leave and salt to appear at the bottom the test ph try to get a 1 or 2 after acidified stop stirring then let it settle you should have two layers again one small one on top and a big on on the bottom now fat out all the salt and upper layer (fatty acids) now change ph to around a 7 by adding small amounts of dilute sodium hydroxide solution (if ph gets to high then add small amounts of dilute hydrochloric acid) once you get about a seven increase heat to about 100C to get out all the water and stir once you have about a 1/3 left stop stirring let salt settle transfer glycerol to another container do not let salt go with it the next step is to add methanol (4x the volume of glycerol) stir once fully dissolved add 6g of activated charcoal let stir for several minutes then vacuum filter it out (could probably do it without the vacuum but it helps got more out) it should now be clear use a distillation system to get out the methanol then (outside the distillation system) stir while at 110C to get the last of the methanol out once cooled it should be pretty viscous and very clear.
