1,3 Butadiene (C4H6)

Nā palena ʻenehana

ʻO ka 1,3-Butadiene he mea hoʻohuihui mea ola me kahi ʻano kemika o C4H6. He kinoea kala ʻole me kahi ʻala ʻala liʻiliʻi a maʻalahi hoʻi e liquefy. He liʻiliʻi ka meaʻawaʻawa a ua like kona ʻona me ka ethylene, akā ua ikaika ka huhū i ka ʻili a me nā mucous membrane, a he hopena anesthetic i nā kiʻekiʻe kiʻekiʻe. ʻO ka 1,3 Butadiene ka mea hiki ke hoʻopili ʻia me ka ea; he maʻalahi ke puhi a pahū ke ʻike ʻia i ka wela, nā ʻulaʻula, nā lapalapa a i ʻole nā ​​​​mea ʻona; inā loaʻa iā ia ka wela nui, hiki mai ka hopena polymerization, e hoʻokuʻu ana i ka wela nui a me ka haki ʻana o ka pahu a me nā pōʻino pahū; ʻOi aku ke kaumaha ma mua o ka ea, hiki iā ia ke pahola i kahi mamao ma kahi haʻahaʻa, a e hoʻihoʻi i ka lapalapa i hope ke hālāwai ʻo ia me kahi lapalapa hāmama. Hoʻopau ʻia ka 1,3 butadiene i ka carbon monoxide a me ka carbon dioxide. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka ethanol a me ka methanol, a hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe organik e like me ka acetone, ether a me ka chloroform. ʻO 1,3 Butadiene he mea pōʻino i ke kaiapuni a hiki ke hoʻohaumia i nā kino wai, ka lepo a me ka lewa. ʻO 1,3 Butadiene ka mea hana nui o ka synthetic rubber (styrene butadiene rubber, butadiene rubber, nitrile rubber, neoprene) a me nā resins like ʻole me ka nui o nā hoʻohana (e like me ABS resin, SBS resin, BS resin, MBS resin) ʻO ka maka He nui nā hoʻohana ʻana o ka butadiene i ka hana ʻana i nā kinikona maikaʻi. Pono e mālama ʻia ka 1,3 butadiene i loko o kahi hale kūʻai maʻalili no nā kinoea lapalapa. E mālama i ke ahi a me nā kumu wela. ʻAʻole pono ka mahana o ka mālama ʻana ma mua o 30 ° C. Pono e mālama ʻokoʻa ʻia mai nā oxidants, halogens, etc., a pale i ka waiho ʻana. E hoʻohana i nā kukui pahū a me nā keʻena ea. ʻAʻole ʻae ʻia ka hoʻohana ʻana i nā mea hana mechanical a me nā mea hana e maʻalahi i nā huna ahi. Pono e hoʻolako ʻia ka wahi e mālama ai me nā lako lapaʻau ulia pōpilikia.

Noi:

①Ka hana ʻana i ka lāʻau synthetic:

ʻO 1,3 Butadiene ka mea maka nui no ka hana ʻana i ka lāʻau synthetic (styrene butadiene rubber, butadiene rubber, nitrile rubber, a me ka neoprene)

②Kemimi kumu kumu:

Hiki ke hana hou ʻia ʻo Butadiene e hana i ka hexamethylene diamine a me ka caprolactam, e lilo ana i mea nui no ka hoʻomākaukau ʻana i ka nylon.

③Kemika maikaʻi:

ʻO nā kinikini maikaʻi i hana ʻia mai ka butadiene ma ke ʻano he kumu.
