Cov hnab looj tes Nitrile yog cov hnab looj tes uas tsim los ntawm kev ua cov khoom siv hluavtaws nitrile (NBR), uas yog muab los ntawm kev sib xyaw ntawm cov molecules sib txawv. Nyob rau hauv cov nqe lus ntawm nitrile roj hmab, chemists muab butadiene thiab acrylonitrile los ntawm ib tug txheej txheem polymerization. Cov molecules no muab cov yam ntxwv ntawm cov hnab looj tes: acrylonitrile txhim kho chemistry, thaum butadiene tsim kev yooj yim thiab tsim kua muag.
