Phenacetylene jẹ ẹya Organic yellow. Eyi ni diẹ ninu awọn ohun-ini ti phenylacetylene:
1. Awọn ohun-ini ti ara: Phenacetylene jẹ omi ti ko ni awọ ti o jẹ iyipada ni iwọn otutu yara.
2. Awọn ohun-ini kemikali: Phenylacetylene le faragba ọpọlọpọ awọn aati ti o ni ibatan si awọn iwe ifowopamọ carbon-carbon meteta. O le faragba ifaseyin afikun pẹlu awọn halogens, gẹgẹbi iṣesi afikun pẹlu chlorine lati dagba phenylacetylene dichloride. Phenacetylene tun le faragba esi idinku, fesi pẹlu hydrogen ni iwaju ayase lati dagba styrene. Phenylacetylene tun le ṣe iṣesi aropo ti awọn reagents amonia lati ṣe agbekalẹ awọn ọja aropo ti o baamu.
3. Iduroṣinṣin: Erogba-carbon meteta mnu ti phenylacetylene jẹ ki o ni iwọn giga ti unsaturation. O jẹ riru jo ati itara si awọn aati polymerization lẹẹkọkan. Phenacetylene tun jẹ ina pupọ ati pe o yẹ ki o yago fun olubasọrọ pẹlu awọn aṣoju oxidizing ti o lagbara ati awọn orisun ina.
Iwọnyi jẹ diẹ ninu awọn ohun-ini ipilẹ ti phenylacetylene, eyiti o ni iye ohun elo pataki ni iṣelọpọ Organic, imọ-jinlẹ ohun elo ati awọn aaye miiran.
