Uses |
Trans-Butene dioic acid is used in the production of unsaturated polyester resins; Trans-Butene dioic acid and vinyl acetate copolymer is a good adhesive, and its styrene copolymer is a raw material for GRP, Trans-Butene dioic acid's plasticizer can be used to produce vinyl polyacetic acid latex. which is the intermediate of drugs and optical bleaching agents. In the pharmaceutical industry for antidote dimercaptosuccinic acid production, will be Trans-Butene dioic acid with sodium carbonate and that are sodium fumarate ([17013-01-3]), and then replaced with ferrous sulfate by Trans-Butene dioic acid iron, which is a medicine of small red blood cells anemia. It can be used as souring agent, which is widely used in Soft drinks, fruit sugar, jelly, ice cream, Trans-Butene dioic acid and NaoH can produce sodium slat, which can be used as souring seasoning; or used as the intermediate of synthetic resin and mordant. |
