Nhanganyaya

Cyclopentadiene (C5H8) imvura isina ruvara uye inonhuwa. Iyo olefin isina kugadzikana yakanyanya polymerized uye ine moto unopisa.

 

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 pakange padeuka netsaona, cheka panobva padeuka nekukasira woichenesa nezvinhu zvakakodzera zvinonyudza. Mukugadzirwa kwemaindasitiri, maitiro ekuchengetedza akakodzera uye matanho anofanirwa kutevedzwa kuti ave nechokwadi chekuchengetedza kushanda.
