The ojiji nke ethylene. ethylene Njirimara

Ethylene bụ mfe nke organic ogige mara dị ka alkenes. Nke a colorless combustible gas, na-enwe a ụtọ uto na isi. Natural enweta na-agụnye eke gas na mmanụ, ọ bụkwa a eke hormone na osisi, ebe ọ na-egbochi uto ma na-akwalite chaa nke mkpụrụ. The ojiji nke ethylene bụ ọsọ na ulo oru organic onwu. Ọ na-arụpụtara site kpo oku eke gas, a agbaze n'ókè nke 169,4 ° C, esi ebe - 103 9 Celsius C.

Ethylene: bughi atụmatụ na Njirimara

Hydrocarbons bụ ụmụ irighiri nwere hydrogen na carbon. Ha dịgasị nnọọ iche na okwu nke ọnụ ọgụgụ nke otu na abụọ agbụ na bughi nghazi nke ọ bụla akụrụngwa. Otu nke mfe, ma biologically na aku na uba uru hydrocarbon bụ ethylene. Ọ na-abịa na a gaseous ụdị, ọ bụ colorless na ukwuu flammable. Ọ mejupụtara abụọ abụọ bonded carbon atọm na hydrogen atọm. The chemical usoro bụ C ₂ H _4. The bughi ụdị molekul bụ linear n'ihi ọnụnọ nke a okpukpu abụọ nkekọ na center.
Ethylene bụ ụtọ musky ísì ụtọ, nke na-eme ka ọ dị mfe ịmata umi na ikuku. Nke a na-emetụta gas dị ọcha ụdị: ísì nwere ike akwụsị mgbe weere na ndị ọzọ ọgwụ.

Scheme ethylene ngwa

Ethylene na-eji na abụọ bụ isi ige: na monomer nke nnukwu carbon ígwè na-rụrụ, na dị ka a akụrụngwa n'ihi ọzọ abụọ-carbon ogige. Polymerization - ugboro a na ijikọta a plurality nke ethylene obere ụmụ irighiri n'ime ibu. Usoro a pụtara na elu nrụgide na okpomọkụ. Ngwa nwere ọtụtụ ethylene. Polyethylene - a polima, nke a na-eji karịsịa na uka mmepụta nke nkwakọ fim, waya coatings, na plastic karama. Ọzọ ojiji nke ethylene ka monomer gbasara guzobere linear α-olefins. Ethylene bụ malite ihe maka nkwadebe nke a ọnụ ọgụgụ nke abụọ-carbon ogige dị ka ethanol (ulo oru mmanya), ethylene oxide (antifirizi, polyester emep uta eri na fim) nke acetaldehyde na vinyl chloride. Tụkwasị na nke a ogige, ethylene na benzene ụdị ethylbenzene, nke na-eji na mmepụta nke plastik na sịntetik roba. The umi na ajụjụ bụ onye nke mfe hydrocarbons. Otú ọ dị, ethylene Njirimara-eme ka ọ na aku na uba na biologically ịrịba.

ethylene Njirimara inye ezi ihe ndabere maka a azụmahịa buru ibu organic (carbon na hydrogen nwere) ihe onwunwe. Single ethylene ụmụ irighiri nwere ike Igbere-emepụta polyethylene (nke pụtara a ọtụtụ ụmụ irighiri nke ethylene). Polyethylene e ji eme ka plastik. Ọzọkwa, ọ ga-eji maka imewe nke detergents, na sịntetik lubricants, nke bụ ọgwụ na-eji belata esemokwu. The ojiji nke ethylene maka styrenes mkpa na oruru nke roba na-echebe nkwakọ. Ke adianade do, ọ na-eji na akpụkpọ ụkwụ ụlọ ọrụ, karịsịa sports akpụkpọ ụkwụ, nakwa dị ka na mmepụta nke ụgbọala na taya. The ojiji nke ethylene bụ commercially mkpa, na gas onwe ya bụ otu n'ime ọtụtụ ugboro ugboro na-emepụta hydrocarbons ụwa.

Health mbibi

Ethylene bụ a ike odachi na akpa ebe n'ihi na ọ bụ ukwuu flammable na-agbawa agbawa. Ọ nwekwara ike-eme ka a ọgwụ na ala kasịnụ, na-eme ọgbụgbọ, dizziness, isi ọwụwa na ọnwụ nke nchikota nke mmegharị.

mmeghachi omume nke ethylene

1) ọxịdashọn. Nke a na mgbakwunye na nke oxygen, e.g., na ọxịdashọn nke ethylene ka ethylene oxide. Ọ na-eji na mmepụta nke ethylene glycol (1,2-ethanediol), nke a na-eji dị ka ihe antifirizi na ke imewe nke polyesters site odide polymerization.

2) Halogenation - mmeghachi omume na ethylene fluorine, chlorine, bromine, ayodiin.

3) chlorination nke ethylene etolite 1,2-dichloroethane na ụdi akakabarede nke 1,2-dichloroethane na vinyl chloride monomer. 1,2-dichloroethane bụ a bara uru organic mgbaze, na bụ a bara uru precursor na njikọ nke vinyl chloride.
4) Alkylation of - agbakwunye hydrocarbons na abụọ nkekọ, ihe atụ, na njikọ nke ethylbenzene si ethylene na benzene, sochiri akakabarede styrene. Ethylbenzene bụ onye n'etiti n'ihi na mmepụta nke styrene, otu n'ime ndị kasị n'ọtụtụ ebe na vinyl monomers. Styrene - monomer eji maka mmepụta nke polystyrene.

5) combustion nke ethylene. The gas nwetara site kpo oku ethyl mmanya na lekwasị na igirigi ibu sulphuric acid.

6) hydration - mmeghachi omume na mgbakwunye na nke mmiri na abụọ nkekọ. Ihe kasị mkpa na ulo oru ngwa a mmeghachi omume bụ na ntughari nke ethylene ka ethanol.

Ethylene na combustion

Ethylene - a gas na-enweghị agba, nke bụ ka ogbonye soluble na mmiri. Combustion nke ethylene na ikuku esonyere guzobe carbon dioxide na mmiri. Dị ọcha ụdị gas Burns ìhè mgbasa ire ọkụ.

7) Ethylene mgbawa na elu kasịnụ.

8) Ethylene na-eji na iko ụlọ ọrụ pụrụ iche zubere maka akpakanamde ụlọ ọrụ.

9) Production nke metal owuwu: gas na-eji dị ka oxygen-manu gas maka metal ọnwụ, ịgbado ọkụ, na elu-ike ọsọ thermal spraying.

10) Oil: ethylene na-eji dị ka refrigerant, karịsịa na mmepụta nke gasị eke gas.

11) Dị ka e kwuru na mbụ, ethylene bụ a ukwuu reactive umi, Ọzọkwa, ọ bụ na-ukwuu flammable. N'ihi na nchekwa ihe mere, ọ na-emekarị ebu pụrụ iche iche iche pipeline.
