Tetramethylsuccinonitrile is a chemical compound from the group of nitriles .
Occurrence
For example, tetramethylsuccinonitrile is formed from amber resin (succinate resin) when exposed to heat . As long as azobis (isobutyronitrile) (AIBN) was still used as an initiator for the polymerization , it was also present in PVC in small amounts .
Extraction and presentation
Tetramethylsuccinonitrile can be obtained from 2,2'-azobis (isobutyronitrile) .
properties
Tetramethylsuccinonitrile is a crystalline, colorless and odorless solid that is practically insoluble in water. It decomposes when heated, producing nitrogen oxides and cyanides .
use
Tetramethylsuccinonitrile is used as a binder for toners .
safety instructions
Tetramethylsuccinitrile is acutely toxic orally, dermally and inhalatively and leads to symptoms of central nervous poisoning. It does not irritate the eyes or the skin.
