He aha te mea te tātai hanganga o te isoprene

He aha te mea isoprene? Ko te tātai whānui o te pūhui haepapa raupapa huirua waiwaro diene, kua he hanganga CnH2n-2. tātari tatou etahi tikanga o te faaineineraa o te pūhui matū, ka kitea i roto i ona te hōkai taketake.

Whakaahuatanga Poto o nga āhuatanga ōkiko

whakarārangi tatou i te āhuatanga ōkiko taketake o te isoprene. Tenei diene pūwaro -toxic, he memehatanga hokiate i roto i te wai. nohanga High o tenei tarukino i pānga whakapōauau. Ko te kukū tīkina mōrahi, te kinokore ki te tangata, kei te whakaaro ki te kia 40 mg / cm ^3. Ki te hua i roto i tenei tohu ko 2-isoprene-1.3 He he pānga tōraro i runga i te konä tangata. I raro i ngā āhuatanga noa, te taonga ko te wai ahua te huitahi he wāhi e koropupu iti.

āhuatanga Rawa matū

He aha faaite te tātai hanganga o te isoprene? e kitea i roto i te hanganga o te pūhui waro rua here rua. tohu ratou nga taunekeneke taketake matū e pūhui diene māngai ki ētahi atu matū organic me inorganic. Kei te tino ngāwari oxidized Isoprene i rangi hāora, ai he peroxides nga hua tauhohenga.

polymerization

E i roto i te polymerization o isoprene? Ko te tātai whānui o te piha haapiiraa ki nei te pūwaro kua te puka CnH2n-2. Ka rite ki te tahi atu i te mau melo o te raupapa huirua o 1,3-butadiene, isoprene ahei o hanga he pūhui nui-rāpoi.

I roto i te whakahaere i te tukanga polymerization o te hanganga o cis me polyisoprene trans, e he analogues o rapa tūturu.

Te faaineineraa o te rapa tūturu

He aha isoprene? Ko te tauhohe e puta i te wa ano e pā ana ki te faafariuraa o te waetahi isoprene i roto i te waerau - polyisoprene. Hoki wehe o rapa tūturu he hanganga rite ki te 2-1,3-metilbutadienom, te tono taherapa o rakau pārūrū.

I waiho i raro i te wai hua ki te maimoatanga vulcanization tënei i roto i te whanariki pūhaumāota. I roto i tenei rapa tauhohenga matū absorbs etahi whanariki, whiwhi plasticity, elasticity. i kainga ki te pāmahana, matū pukuriri te hua polymerization. whakamārama te tātai hanganga o te isoprene nga āhuatanga rere o te tukanga vulcanization.

Ki te ki tenei pāhekoheko matū tango te whanariki i te whānuitanga o te 25 ki te 40 ōrau, e taea te whiwhi he eponi. Kua nui te kaha, whakamahia tēnei rauemi kei te rite te rauemi tuuraa i pai. Ko te tātai hanganga o te isoprene, i haere mai ki te whakapā ki te whanariki, kei kahore here rua. E whakamārama ana te hanganga hua me tona kaha aunoa.

rubbers Polyisoprene kitea waerau katoa whakamahia i roto i te hanga o te waka rererangi, pereoo, ruma pahikara me potae.

He aha atu e nehenehe e korero isoprene tātai hanganga? Ko reira, e nehenehe o te tua tauhohe o te here rua ki ngā rāpoi ngota galogenovdorodov, kōnakonako, hauwai, te wai. Ēnei tauhohe whakamatau isoprene no ki te piha haapiiraa o waiwaro hamanga.

Methods mo te faaineineraa ahumahi o

He maha ngā tikanga o te hanga ahumahi o isoprene. Hoki tauira, mā te tauhohe i acetylene ki hauwaiwaro tauhohenga tā hanganga o metibutinola takawaenga. I muri i tona hydrogenation, aru i te maroketanga o te isoprene hua. Ko reira taea hoki ki te whiwhi 2-methylbutadiene-1,3 propylene. I roto i te kōwhiringa o kaiwhakakökï taea te tāpiri rite matū atu ki te farii i te mewaro.

Ko te whakamahi o te isoprene

Kei te whakamahia te nuinga o te isoprene hua mo te kōtuitui o isoprene rapa. Ko ia tinana, me te he tata ōrite ki ngā rauemi māori āhuatanga matū. ka karanga tono atu o te pūhui nui-rāpoi oti te hanga o potae pereoo.

I tua atu ki te cis-poinanaha, i roto i nga hua polymerization reira he ano te poinanaha trans, he nga āhuatanga o te gutta percha. E ia kahore tono ahumahi motuhake. Ko tēnei rauemi polymeric ko ki te waihanga i tētahi pōro mo te kēmu o te korowha rite te pai kia rite ki mo te hanga o te mātao o waea hiko. I roto i te rāngai nui tono e taea e ariā isoprene taiea o ngā rauemi polymeric te hanga i te styrene-isoprene-styrene. Kei te whakamahia Products o tenei momo rite rauemi rewarau, adhesives, pēhanga tairongo.

hiahiatia Isoprene te mo te kōtuitui o butyl rapa, tona ihirangi ine i roto i reira mai ki te toru ōrau.

Mai te mutunga o te rau tau whakamutunga i roto i te United States kua timata production arumoni o terpenes i te ranunga kai o isoprene, acetylene, hauwaiwaro. Te hangarau, e hāngai ana nei i runga i tenei tikanga, e pā ana i te kōtuitui e rua-taahiraa.
