Dimethyl adipate is a chemical compound from the group of carboxylic acid esters .
Occurrence
The fringed winged Echinothrips americanus uses dimethyl adipate and dimethyl glutarate as pheromones.
Extraction and presentation
Dimethyl adipate can be obtained by esterification of adipic acid with methanol or by hydroesterification of butadiene with a cobalt catalyst.
properties
Dimethyl adipate is a flammable, difficult to ignite, colorless liquid with a sweet odor. Information in the literature that dimethyl adipate is sparingly soluble in water is probably incorrect. However, there is a wide range of other information between 6 g / l, 14 g / l (at 25 ° C) and 25 g / l (at 20 ° C).
use
Dimethyl adipate is used in cosmetics as an emollient and for skin conditioning . It is also used in agrochemicals and dyes, as well as a precursor for the manufacture of active pharmaceutical ingredients and as a component of dibasic ester .
