Kupu Whakataki

I mua, i whakaarohia te Methyl tert-butyl ether (MTBE) hei wāhanga penehīni octane-teitei e kore e taea te whakakapi, ā, i huaina ko te "matū matū matū tuatoru o te whakatupuranga" i ngā tau 1980. Nā te mea ka taea e ia te whakanui ake i te nui o te hāora o te penehīni kore-ārahi, te whakakā i te penehīni, te whakaiti i te tukunga o ngā matū kino pēnei i te waro monoxide me te benzene, ā, ka taea te whakakapi i te mata tetraethyl hei kaihoko ārai-riot, ka tutuki i a ia ngā whakaritenga mō te whakaputa penehīni kore-ārahi octane-teitei. , ka tere te tipu o tōna hiahia, he tāpiringa penehīni octane-teitei pai rawa atu mō Chemicalbook. He wāhanga whakaranu pai te MTBE mō te whakaputa penehīni kore-ārahi, octane-teitei, me te hāora. Kāore e taea anake te whakanui ake i te maha octane o te penehīni, engari ka whakapai ake hoki i te mahi a te waka, te whakaiti i te nui o te CO i roto i te hau putanga, me te whakaiti i ngā utu whakaputa penehīni. Hei tāpiri, he rauemi mata matū nui anō hoki te methyl tert-butyl ether, ka taea te wawahi anō ki te isobutylene me te whakamahi hei rauemi mata mō te rapa me ētahi atu hua matū. I tēnei wā, e mārama ana kei te whakaiti te MTBE i te ngoikore o te hiko.

Ngā āhuatanga ā-tinana me ngā āhuatanga matū:

Ko te Methyl tert-butyl ether, e whakarapopototia ana ko MTBE (methyltert-butylether), he -109°C te pāmahana rewa, ā, he 55.2°C te pāmahana koropupū. He wai mārama, kore tae, he nui te octane, he kakara rite ki te ether. He mea hanga tēnei Chemicalbook hei wāhanga whakaranu pai mō te penehīni kore-mata, nui te octane, he hāora, ā, kua whānuitia te whakamahinga hei tāpiri penehīni puta noa i te ao. Ehara i te mea ka taea anake te whakanui ake i te tau octane o te penehīni, engari ka whakapai ake hoki i te mahi a te waka, te whakaiti i te nui o te CO i roto i te hau putanga, me te whakaiti i ngā utu whakaputa penehīni.

Whakamahinga

Ko te Methyl tert-butyl ether (MTBE) te nuinga o te wā e whakamahia ana hei tāpiringa penehīni, ā, he tino pai ngā āhuatanga ārai-patuki. He pai te whakaranu ki te penehīni, he iti ake te mimiti i te wai, ā, kāore e whakapoke i te taiao. Ka taea e te MTBE te whakapai ake i ngā āhuatanga tīmatanga makariri me te mahi whakaterenga o te penehīni me te kore e pā kino ki te raka kohu. Ahakoa he iti te uara wera o te methyl tert-butyl ether, kua whakaatuhia e ngā whakamātautau taraiwa ka taea e te whakamahi i te penehīni kei roto ko te 10 Chemicalbook% MTBE te whakaiti i te whakapaunga wahie mā te 7% me te whakaiti nui i te nui o te mata me te CO i roto i te hau putanga, inā koa ko ngā tukunga o ngā hauwaiwaro kakara polycyclic carcinogenic. whakaiti. Hei rauemi mata mō te hanga rauropi, ka taea te whakaputa isobutylene parakore teitei. Ka taea hoki te whakamahi hei whakaputa 2-methacrolein, waikawa methacrylic me te isoprene, me ētahi atu. Hei tāpiri, ka taea hoki te whakamahi hei whakarewa tātari me te kaihoko tango.

Ka whakamahia e te tikanga whakaputa te ranunga o te butene me te methanol hei rauemi mata, ā, ka mahia he tauhohenga werawera i te aroaro o tētahi whakakorikori waikawa.
