Production methods
Industrial production methods can be grouped into two categories:
derived from the saponification or high temperature and pressure decomposition of natural vegetable oils and fats;
separated from the synthetic fatty acid.
Japan mainly uses coconut oil and palm kernel oil as the raw materials for the preparation of Lauric acid.
The natural vegetable oils used to produce Lauric acid include coconut oil, litsea cubeba kernel oil, palm kernel oil and mountain pepper seed oil.

Derived from the separation and purification of coconut oil and other vegetable oil.
Lauric acid naturally exists in coconut oil, litsea cubeba kernel oil, palm kernel oil and pepper kernel oil in the form of glyceride.
Lauric acid can be derived from the hydrolysis of natural oils and fats in industry.
The coconut oil, water and catalyst are added into the autoclave and hydrolyzed to glycerol and fatty acid at 250 ℃ under the pressure of 5MPa.
The content of Lauric acid is 45%~80%, and can be further distilled to obtain dodecanoic acid.
Production Methods
Lauric acid is a fatty carboxylic acid isolated from vegetable and animal fats or oils.
For example, coconut oil and palm kernel oil both contain high proportions of Lauric acid.
Isolation from natural fats and oils involves hydrolysis, separation of the fatty acids, hydrogenation to convert unsaturated fatty acids to saturated acids, and finally distillation of the specific fatty acid of interest.
Production and reactions
Lauric acid is mainly isolated from natural sources.
Lauric acid's reactions are representative of those of similar long chain, saturated fatty acids.
Lauric acid can be converted to the symmetrical fatty ketone called laurone (O=C(C11H23)2).
Lauric acid transesterifies with vinyl acetate.
Treatment with sulfur trioxide gives the α-sulfonic acid.
Reactivity Profile
Lauric acid is a carboxylic acid.
Carboxylic acids donate hydrogen ions if a base is present to accept them.
They react in this way with all bases, both organic (for example, the amines) and inorganic.
Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat.
Neutralization between an acid and a base produces water plus a salt.
Lauric acid's in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt.
Such reactions occur in principle for solid Lauric acid's as well, but are slow if the solid acid remains dry.
Even "insoluble" Lauric acid may absorb enough water from the air and dissolve sufficiently in Lauric acid to corrode or dissolve iron, steel, and aluminum parts and containers.
Lauric acid, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide.
The reaction is slower for dry, solid Lauric acid.
Insoluble Lauric acid react with solutions of cyanides to cause the release of gaseous hydrogen cyanide.
Flammable and/or toxic gases and heat are generated by the reaction of Lauric acid with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides.
Lauric acid, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat.
Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat.
Like other organic compounds, Lauric acid can be oxidized by strong oxidizing agents and reduced by strong reducing agents.
These reactions generate heat.
A wide variety of products is possible.
Like other acids, Lauric acid may initiate polymerization reactions; like other acids, they often catalyze (increase the rate of) chemical reactions.
Lauric acid can react with oxidizing materials.
