Isticmaalka ethylene. guryaha ethylene

Polymer waa ka ugu fudud xeryahooda organic yaqaan alkenes. Tani Biyuhu gaaska guban kara, isagoo dhadhan macaan iyo urta. ilaha dabiiciga ah waxaa ka mid ah gaaska dabiiciga ah iyo saliid, sidoo kale waa hormone dabiici ah in dhirta, halkaas oo uu hakiyo koritaanka iyo kor u fulan midhaha. Isticmaalka ethylene waa wax caadi ah in chemistry organic warshadaha. Waxaa la soo saaray by kulaylinta gaaska dabiiciga ah, barta barafku ka mid ah 169,4 ° C a, karkaraya dhibic - 103 9 ° C.

Polymer: muuqaalada dhismaha iyo guryaha

Consort waa u taagoo kooban hydrogen iyo carbon. Aad bay u kala duwan yihiin marka la eego tirada bonds hal iyo labo gool iyo hanuuninta dhismaha ee qayb kasta. Mid ka mid ah fudud, laakiin bayoloji iyo dhaqaale ahaan faa'iidada hydrocarbon waa ethylene. Waxay ku timaadaa qaab gas, waa midab iyo aadka u ololi kara. Waxay ka kooban tahay laba atamka carbon addoonsi double la atamka hydrogen. formula kiimikada waa C ₂ H _4. Foomka dhismaha ee Britain waa toosan sabab u ah joogitaanka bond a double ee xarunta.
Polymer waa ur musky macaan, taas oo waa wax fudud si ay u aqoonsadaan maalkii hawada. Tani waxay khusaysaa gaaska qaab saafi ah; ur baaba'aan marka kiimikooyin kale lagu daray.

codsiyada ethylene Scheme

Polymer waxaa loo isticmaalaa in laba qaybood oo aasaasi ah: monomer ka silsilado carbon weyn loo dhisay, iyo qalab ceeriin for xarumaha kale ee laba-carbon. Polymerization - ku cel-celinta this isku hannaanka a of ethylene taagoo yar gelin weyn. Marxaladani waxay dhacdaa at cadaadis sarreeya iyo heerkulka. Araajida waa ethylene badan. Polyetylen - polymer ah, taas oo loo isticmaalayo si gaar ah ee wax soo saarka ballaaran ee filimada baakooyinka, blaastiigga silig, iyo dhalooyin caag ah. Isticmaalka kale oo ethylene sida monomer ku saabsan dhismaha toosan α-olefins. Polymer waa wax laga bilaabo diyaarinta tiro ka mid ah xeryahooda laba-carbon sida ethanol (khamriga warshadaha), xabagta ethylene (qabow ka hor taga, fiiloyin caag iyo filimada) ee acetaldehyde iyo chloride vinylalkohol. Waxa intaa dheer in kuwan xeryahooda, ethylene iyo foomka benzene ethylbenzene, taas oo loo isticmaalayo in wax soo saarka ee balaastigga iyo caag synthetic. walaxda in su'aasha ah waa mid ka mid ah Consort fudud. Si kastaba ha ahaatee, guryaha ethylene dhigo mid dhaqaale ahaan iyo bayoloji weyn.

isticmaalka ganacsiga

guryaha ethylene ay sal wanaagsan oo tiro ganacsi oo badan oo ah organic (carbon oo ka kooban hydrogen) wax. taagoo ethylene Single waxaa laga yaabaa in si wadajir ah u soo saaraan polyetylen (taas oo macnaheedu yahay wax badan oo u taagoo of ethylene). Polyetylen loo isticmaalo si ay u sameeyaan bacyaal. Intaas waxaa sii dheer, waxaa loo isticmaali karaa soo saaridda of saabuun, iyo saliidaha dardaro, kuwaas oo ah kiimikada loo isticmaalo si loo yareeyo khilaafka. Isticmaalka ethylene for styrenes muhiim ah in la aasaaso caag iyo baakadaha ilaaliya. Intaa waxaa dheer, waxaa loo isticmaalaa in industry kabaha, gaar ahaan kabaha sports, iyo sidoo kale wax soo saarka ee taayirada baabuurta. Isticmaalka ethylene waa ganacsi oo muhiim ah, iyo gaaska laftiisa waa mid ka mid ah Consort inta badan soo saaray caalami ah.

Khataraha Caafimaadka

Polymer waa halis caafimaad ee meesha ugu horeysa ah, sababtoo ah waa heer sare ah ololi kara iyo waxyaabaha qarxa. Waxa kale oo ay noqon karaan daroogada a at uruuray hooseeyo, taasoo keenta lallabo, dawakhaad, madax xanuun iyo khasaaro of isuduwidda dhaqdhaqaaqa. At uruureen sare, ay u dhaqmo sida suuxinta, taasoo keenta miyir, Saylici waxa xanuunka iyo meersan kale. Oo kulli intaas oo dhinacyo negative noqon kartaa sabab walaac gaar ahaan loogu talagalay dadka si toos ah ula shaqeeyaan gaaska. Inta ay ethylene, oo dadka intooda badan waxaa soo food saartay in nolol maalmeedka, sida caadiga ah waa yar.

falcelinta of ethylene

1) qayilo. Tani waxaa dheer of ogsijiin, tus, in lagu qayilo ee ethylene in xabagta ethylene. Waxa loo isticmaalaa in wax soo saarka ee tones ethylene (1,2-ethanediol), kaasi oo loo adeegsaday sida qabow ka hor taga iyo soo saaridda ee polyesters dhex polymerization uumiga.

2) Halogenation - cadaanyo la fluorine ethylene, chlorine, bromine, iodine.

3) koloriin The of ethylene si ay u sameeyaan 1,2-dichloroethane iyo diinta ka ku xiga ee 1,2-dichloroethane in monomer chloride vinylalkohol ah. 1,2-dichloroethane waa dareeraha organic waxtar leh, oo waa maamaan ah oo qiimo leh in ereygu wuxuu ahaa ee chloride vinylalkohol.
4) Alkylation ah - isagoo intaa ku daray in Consort debaajiga double, tusaale ahaan, ereygu wuxuu ahaa ee ethylbenzene ka ethylene iyo benzene, raaceen by beddelidda, si ay styrene. Ethylbenzene waa dhexdhexaad ah wax soo saarka ee styrene, mid ka mid ah monomers vinylalkohol ugu ballaaran loo isticmaalo. Styrene - monomer loo isticmaalo wax soo saarka ee polystyrene.

5) sari ee ethylene. gaas ka helay by kulaylinta khamriga ethyl iyo xoog sulfuric acid.

6) fuuq - falcelinta dheeriga ah oo biyo ah si ay nafteeda ku double. Codsiga ugu muhiimsan warshadaha cadaanyo tani waa qaab beddelidda of ethylene in ethanol.

Polymer iyo sari

Ethylene - gaaska leh midab lahayn, taas oo si liidata L. biyo. Sari of ethylene hawada la socda formation of carbon dioxide iyo biyo. In saafi ah qaab gaas gubasho Nuur olol sida-. Qaso qadar yar oo ah hawada, waxa uu siiyaa ololkii, kaas oo ka kooban saddex lakab oo kala duwan - xudunta hoose - gaaska unburned, lakabka buluug-cagaaran iyo koorta dibadda, kuna waari dhexdeeda sheyga qayb oxidized of lakabka pre-isku qasan lagu gubay olol sida- ah. ololkii meesha sababtay muujinaysaa taxane ah oo adag oo dareen diidmo, iyo haddii ey isku gaaska lagu daraa dheeraad ah lakabka sida- hawada si tartiib tartiib ah u baaba'aa.

Mudan

1) polymer waa hormoon dhirta dabiiciga ah, waxa ay saamayn ku koritaanka, horumarka, koriinkedu iyo gabowga ah ee dhirta.

2) Gas ma aha waxyeello oo aan sun ugu ah dadka at-fiirsashada gaar ah (100-150 mg).

3) Waxa loo isticmaalaa in daawada sida xanuunka ah.

4) tallaabo ethylene hoos at heerkulka hoose.

5) feature A caan ku yahay wax lays wanaagsan walxaha ugu, tusaale ahaan iyada oo sanduuqyada xirxirida kartoonada, qoryo iyo xataa darbiyada la taaban karo.

6) Iyadoo ay tahay mid qiimo ah ee ay awoodda in la bilaabo geeddi-socodka ah ee koriinkedu, waxa ay sidoo kale noqon karaan kuwo aad halis u ah midhaha badan, khudaarta, ubaxa iyo dhirta, sare u geedi socodka gaboobaya iyo yaraynta tayada wax soo saarka iyo nolosha shelf ay. xaddiga burbur ee ku xiran fiirsashada, duration gaadhista iyo heerkulka.

7) ethylene qarxa at uruuray sare.

8) ethylene waxaa loo isticmaalaa in industry muraayadda ujeedooyin gaar ah oo suuqa baabuurta.

9) Production dhismayaasha birta ah: gaaska waxaa loo isticmaalaa sida gaaska oxygen-Shidaalka goynta biraha, alxanka, iyo xawaare sare ku xereen kaamerada ah.

10) Oil: ethylene waxaa loo isticmaalaa sida refrigerant ah, gaar ahaan wax soo saarka ee gaaska dabiiciga ah la galeen.

11) Sidii hore loo soo xusay, ethylene waa shay aad u falceliya, weliba, sidoo kale waa heer sare ah ololi kara. Sababo nabadgelyo, waxaana badanaa la qaadaa dhuunta oo kala duwan gaar ah.

12) Mid ka mid ah waxyaabaha ugu badan ee si toos ah macmalay ka ethylene waa caag ah.
