Synonym(s): TMP Trioleate, 2-ethyl-2-(hydroxylmethyl)propane-1,3,-diol trioleate.

Description

CG 403 is made by reacting trimethylolpropane with oleic acid. The formula of the product is CH3CH2C(CH2OOCC17H33)3. CG 403 has excellent lubricity, high viscosity index, and is biodegradable. It is widely used as a base stock in flame resistant hydraulic fluids and metal-working fluids. It is also used in many environmentally friendly oils due to its biodegradability.

Applications

TMPTO is used for many applications, which include, but are not limited to,

Synthetic ester base oil for water-free, flame-resistant hydraulic fluids, particularly for ISO 46 hydraulic fluids.
Biodegradable hydraulic fluids, chain saw oils, and engine oils.
Rolling oils, drawing oils and metal-working fluids.
Additives for textile products.

Manufacturing Process

Industrial TMPTO, trimethylolpropane trioleate, is manufactured by reacting trimethylolpropane, commonly known as TMP, with oleic acid, in the presence of an acid catalyst.

Chemical Reactions

TMPTO is usually used as an end product in multiple applications, and it is not typically used as a chemical intermediate. However, TMPTO may not be stable under strong acidic or basic conditions, particularly when water or moisture is present. In these cases, TMPTO tends to be hydrolyzed into trimethylolpropane and oleic acid.
