| introduction | dimethyl glutarate slightly aromatic liquid, colorless and transparent liquid at room temperature, soluble in alcohol and ether, insoluble in water, is an environment-friendly high boiling point solvent, with low volatilization, easy flow, safety, non-toxic, photochemical stability and other characteristics. |
| application | dimethyl glutarate is widely used in automobile coatings, color steel plate coatings, can coatings, enameled wires and household appliance coatings. it is also an important intermediate of fine chemicals and is used to prepare polyester resins, adhesives, synthetic fibers, membrane materials, etc. |
| preparation | a method for separating dimethyl succinate and dimethyl glutarate from dibasic acid esters, which is characterized by following the following process: in the first step, dibasic acid ester raw materials are passed through dimethyl succinate distillation tower, I .e. the first tower to separate dimethyl succinate products, I .e. the light component dimethyl succinate products are separated from the top of the first tower, and the recombinant component is separated from the bottom of the first tower; in the second step, the recombinant component separated in the first step is separated into the new dibasic acid ester product through the dimethyl glutarate pre-distillation tower, the second tower, that is, the light component is separated from the top of the second tower, and the recombinant component is the new dibasic acid ester product is obtained from the bottom of the second tower; the third step is to separate the light and heavy components separated in the second step through the dimethyl glutarate distillation tower, the third tower, to separate the dimethyl glutarate product, namely: its light components were separated from the top of the third tower, and its recombinant component, dimethyl glutarate product, was obtained from the bottom of the third tower. |
| Use | Mainly used in organic synthesis |
