Ga na polymerization nke isoprene? The n'ozuzu usoro nke klas nke hydrocarbon nwere ụdị CnH2n-2. Dị ka ndị ọzọ so homologous usoro nke 1,3-butadiene, isoprene ike nke na-akpụ a elu-molekụla compound.

N'ịrụzu polymerization usoro nke guzobere CIS na trans polyisoprene, nke bụ analogues nke eke roba.

Nkwadebe nke eke roba

Gịnị isoprene? The mmeghachi omume na-erukwa n'otu oge ndị a na-akakabarede nke isoprene monomer na polima - polyisoprene. N'ihi na iche nke eke roba na-enwe a Ọdịdị yiri 2-1,3-metilbutadienom, tinye latex nke ebe okpomọkụ osisi.

The polymerization ngwaahịa bụ mụ na okpomọkụ, ike ike kemịkal. The bughi usoro nke isoprene akọwa eruba e ji mara nke vulcanization usoro.

Ọ bụrụ na nke a chemical mmekọrịta na-sọlfọ na nso nke 25 ruo pasent 40, pụrụ inweta ojii. Nke a ihe onwunwe elu ike, na-eji dị ka ihe magburu onwe-egbochi ihe onwunwe. The bughi usoro nke isoprene, nke bịara na kọntaktị na sọlfọ ahụ, nwere dịghị abụọ agbụ. Ọ na-akọwa ngwaahịa Ọdịdị na ya n'ibu ike.

Olee ihe ọzọ nwere ike ịgwa bughi usoro isoprene? Ọ bụ ike nke na mgbakwunye na mmeghachi omume nke abụọ nkekọ na ụmụ irighiri galogenovdorodov, halogens, hydrogen, mmiri. Mmeghachi omume ndị a na-egosi isoprene nke a na klas nke unsaturated hydrocarbons.

Ụzọ maka ulo oru nkwadebe nke

E nwere ọtụtụ ụzọ nke ulo oru na mmepụta nke isoprene. Ka ihe atụ, site na omume acetylene na acetone mmeghachi omume na-agụnye guzobere n'etiti metibutinola. Mgbe ya hydrogenation, sochiri akpịrị ịkpọ nkụ nke na-emepụta isoprene. Ọ dịkwa ike iji nweta 2-methylbutadiene-1,3 propylene.

The ojiji nke isoprene

Otutu nke na-emepụta isoprene na-eji maka njikọ nke isoprene roba. Ọ bụ na ahụ na chemical e ji mara bụ fọrọ nke nta yiri ka eke ihe. Ọzọ ngwa nke okokụre elu-molekụla compound akpọ imewe nke ụgbọala na taya.

Ke adianade CIS-isomer, n'etiti polymerization ngwaahịa e nwekwara ndị trans isomer, inwe àgwà nke gutta percha. Ọ dịghị pụrụ iche ulo oru ngwa. Nke a polymeric ihe onwunwe bụ ike a bọl maka egwuregwu nke golf nakwa dị ka n'ihi na mmepụta nke mkpuchi nke electric wires. Otu n'ime ihe ndị dị mkpa ngwa ndi nwere ike ịbụ na-akwanyere ùgwù isoprene njikọ nke polymeric ihe na-etolite a styrene-isoprene-styrene. Ngwaahịa nke ụdị na-eji dị ka thermoplastic ihe, adhesives, nrụgide mmetụta ọsọ ọsọ.
