The oil is heated and the methoxide is mixed in and the chemical reaction begins.

What chemicals are used to make biodiesel. It is typically made by chemically reacting lipids such as animal fat tallow soybean oil or some other vegetable oil with an alcohol producing a methyl ethyl or propyl ester by the process of transesterification. Polymers include flexible foams and rigid foams alkyl resins plastics and cellophane surface coatings and paints and as a softener and plasticizer. Biodiesel is a form of diesel fuel derived from plants or animals and consisting of long-chain fatty acid esters.

Sometimes with waste oil there can be all kinds of weird contaminants that the titration test wont pick up on so just to be on the safe side we test the oil once more by making a mini batch in a mason jar watching very carefully how quickly. However only an efficient catalyst can significantly accelerate the reaction rate. Waste vegi oil WVO NaOH lye and methanol.

The type of alcohols used for biodiesel production receive less attention than the catalyst type due to the fact that the alcoholysis reaction can be carried in the presence of short- or long-chain monohydric alcohols. Either Potassium Hydroxide KOH or Sodium Hydroxide NaOH. Please read up on this before you start and please.

When the transesterification process is complete the catalyst can be recovered completely unaffected by the chemical reaction that it helped accelerate. To make Biodiesel a catalyst is needed. The catalyst is then dissolved into methanol to create what is called methoxide.

B5 and B20 are common biodiesel blends. The process for making biodiesel uses an oil a catalyst and an alcohol. We carry all the chemicals you need to make biodiesel.

Glycerol is also used to make a variety of polymers particularly polyether polyols. The titration that we did in step 1 is a really good indication of how much chemicals to use to get a good biodiesel reaction but it is not fool proof. The type of processes and equipment used to make the biodiesel is determined by the feedstocks you plan to use in producing the biodiesel.
