Nhanganyaya

Styrene, imvura isina ruvara ine kunhuhwirira kwakakosha. Inotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza styrene:

Hunhu:

1. Lighter density.

2. Inoshanduka patembiricha yekamuri uye ine yakaderera flash point uye inoputika.

3. Inosanganiswa nemhando dzakasiyana-siyana dzeorganic solvents uye yakakosha zvakanyanya organic substance.

Shandisa:

1. Styrene ikemikari inokosha yakasvibiswa, inowanzoshandiswa mukugadzirwa kwenhamba yakawanda yemapurasitiki, synthetic rubber uye fibers.

2. Styrene inogona kushandiswa kugadzira zvinhu zvekugadzira zvakadai sepolystyrene (PS), polystyrene rubber (SBR) uye acrylonitrile-styrene copolymer.

3. Inogona zvakare kushandiswa kugadzira zvigadzirwa zvemakemikari senge zvinonaka uye mafuta ekuzora.

Nzira:

1. Styrene inogona kuwanikwa ne dehydrogenation nekupisa uye kudzvinyirira ethylene molecules.

2. Styrene uye hydrogen zvinogonawo kuwanikwa nekupisa uye kuputika ethylbenzene.

Zvekuchengetedza

1. Styrene inopisa uye inofanira kudzivirirwa kubva pakupisa uye kupisa kwakanyanya.

2. Kubata neganda kunogona kukonzera kutsamwa uye kusawirirana, uye matanho akakodzera anofanira kutorwa.

3. Kuratidzwa kwenguva refu kana kuti kwakanyanya kunogona kuva nemigumisiro yakaipa yehutano, kusanganisira kukanganisa kwepakati petsinga, chiropa, uye itsvo.

4. Chenjerera kumhepo yemhepo paunenge uchishandisa, uye dzivisa kufemesa kana kupinza.

5. Kuraswa kwemarara kunofanirwa kutevedzera mitemo nemirau yakakodzera, uye hakufanirwe kuraswa kana kuburitswa pamadiro.

Zvakapfuura: Phenylacetylene(CAS#536-74-3)

Zvinotevera: Phenylacetyl chloride(CAS#103-80-0)
