Uses: γ--butyrolactone is an important chemical intermediates> while also a good performance of high boiling solvent, that is preferably an antioxidant, a plasticizer, extraction agents, absorbents, dispersing agents, sticking agent, coagulant it has a high boiling point, strong solvency, good electrical conductivity and stability, convenient to use and manage security advantages. Through the open-loop or open-loop chemical reaction, producing a variety of fine chemicals, and there are many kinds of important heterocyclic compounds, widely used in medicine, pesticides, synthetic resin additives, food feed additives, dyes and pigments, electronics and so on in the field .
1 Industrial:
(A) synthetic pyrrolidone series products. Can be used in the manufacture a- pyrrolidone, N- methylpyrrolidone, N- ethyl pyrrolidone, polyvinyl pyrrolidone and the like;
(2) extraction agent petrochemical industry. Additives for absorbing alkynes, aromatic hydrocarbons, alcohols and cyclic ether extraction agent, lubricating oil additives;
(3) synthetic fiber spinning solvent, setting agent, dyeing auxiliary, an antistatic agent. The solvent used for spinning acrylic fibers and solidification of the solvent, the cellulose ester of wool, nylon dyeing auxiliaries, nylon fibers, antistatic agents;
(4) a synthetic resin ideal antioxidant, a plasticizer, a dispersing agent, a fixing agent and a solvent. Used as a polypropylene, polyvinyl chloride, polystyrene solvent dispersant polyvinyl fluoride, a variety of resin dyeing modifiers, antioxidants, plasticizers and the like;
(5) is the raw material for the production of perfume, ink lubricants and rust agents.
