21. Other materials used to alleviate this are PVC, nitrile , and neoprene. 22. Nitrile rubber is less likely to cause an allergic reaction than natural rubber.23. Also thanks for the advice for wearing nitrile gloves. 24. That's exactly how nitrile hydrolysis works ( see link above ). 25. The compound contains two functional groups, a nitrile and a carboxylic acid. 26. Organic nitriles do not readily release cyanide ions, and so have low toxicities. 27. Similar considerations apply in the Kolbe nitrile synthesis. 28. The determining factor is typically how electron-rich or poor the nitrile is. 29. The seeds contain nitriles , which are common in seeds of the rose family. 30. The reaction is caused by the latex or the nitrile present in the gloves.
