Nhanganyaya

Cyclopentadiene (C5H8) imvura isina ruvara uye inonhuwa. Iyo olefin isina kugadzikana zvakanyanya iyo ine polymerized uye inobvira kupisa.

Cyclopentadiene ine zvakawanda zvakasiyana-siyana zvekushandisa mukutsvakurudza kwemakemikari. Inogona zvakare kushandiswa seyakagadzirwa zvinhu zvepolymers uye rubber kuvandudza iwo emuviri uye makemikari zvimiro.

Kune nzira mbiri huru dzekugadzirira cyclopentadiene: imwe inogadzirwa kubva pakuputika kwemafuta eparafini, uye imwe inogadzirirwa neisomerization reaction kana hydrogenation reaction yeolefins.

Cyclopentadiene inoputika uye inopfuta, uye imvura inopisa. Muchiito chekuchengetedza uye chekufambisa, moto uye kuputika matanho ekudzivirira anofanira kutorwa kuti usasangana nemoto wakazaruka uye kupisa kwakanyanya. Pfeka midziyo yekudzivirira yakakodzera senge magirovhosi, magirazi, uye zvipfeko zvinoputika paunenge uchishandisa nekubata cyclopentadiene. Panguva imwecheteyo, kutarisirwa kunofanira kutorwa kuti usasangana neganda uye inhalation yemhepo yaro, kuitira kuti irege kukonzera kutsamwa uye chepfu. Kana pakadonhera netsaona, cheka panobva padeuka nekukasira woichenesa nezvinhu zvinonyura zvakakodzera. Mukugadzirwa kwemaindasitiri, maitiro ekuchengetedza akakodzera uye matanho anofanirwa kutevedzwa kuti ave nechokwadi chekuchengetedza kushanda.

Zvakapfuura: Cyclohexanone(CAS#108-94-1)

Zvinotevera: Cyclopentanone(CAS#120-92-3)
