Boiling point ye toluene: nzwisiso mune ino yakajairika kemikari chinhu
Toluene, seyakashandiswa zvakanyanya organic compound muindasitiri yemakemikari, inoita basa rakakosha muminda yakawanda ine hunhu hwayo hwakasiyana. Iyo yekubikira poindi ye toluene ndiyo yakakosha parameter inoda kutariswa kwakanyanya mukugadzirwa kwemaindasitiri uye mashandisirwo. Kunzwisisa nzvimbo yekubikira ye toluene haingoraidzi chete kuchengetedza kwayo uye kutakura, asiwo kwakakosha pakudzora tembiricha panguva dzakasiyana siyana dzemakemikari.
Mhedziso yezvakakosha zvivakwa uye yekubikira poindi ye toluene
Toluene imvura isina ruvara, inonhuhwirira ine kemikari formula C₇H₈. Inowanikwa zvakanyanya mumapendi, machira, matete uye zvinonamira uye zvakare inowanzoshandiswa seyakagadziriswa maindasitiri. Pamhepo yemhepo, panovira toluene i110.6°C. Iyi nzvimbo yakadzikira yekubikira inobvumira kuti toluene inyunguduke zviri nyore patembiricha yekamuri, saka kutariswa kwakanyanya kunoda kubhadharwa pakusagadzikana kwayo uye njodzi dzinogona kuitika dzemhute panguva yekushanda.
Zvinhu zvinokanganisa kuvira kwe toluene
Kunyange zvazvo nzvimbo yekuvira ye toluene iri 110.6 ° C pamhepo yemhepo, iyi parameter inogona kukanganiswa nezvinhu zvakasiyana-siyana mumashandisirwo anoshanda. Semuenzaniso, shanduko mukumanikidza inogona kukanganisa zvakananga nzvimbo yekubikira ye toluene. Maererano nemutemo wegesi, nzvimbo yekubikira yemvura inokwira kana kuwedzera kunowedzera; zvakasiyana, inowira apo kudzvinyirira kunoderera. Ichi chiitiko chinoshandiswa zvakanyanya mumaindasitiri distillation uye kugadzirisa maitiro ekugonesa mashandisirwo esimba uye goho mukuparadzanisa maitiro.
Kuchena zvakare chimwe chezvinhu zvakakosha zvinokanganisa nzvimbo yekubikira ye toluene. Mukugadzirwa kwemaindasitiri, toluene kazhinji ine zvimwe zvitsvina, kuvapo kwacho kunogona kutungamira kukuchinja kudiki munzvimbo yekubikira ye toluene. Naizvozvo, kunzwisisa uye kudzora kuchena kwetoluene kwakakosha kuti uwane nemazvo nzvimbo yekuvira kwayo.
Toluene boiling point muindasitiri
Mukugadzirwa kwekemikari, nzvimbo yekuvira ye toluene inowanzoshandiswa kuona nguva yetembiricha iri pakati pekubuda kwayo nekudzika kwayo, izvo zvinonyanya kukosha pakupatsanurwa kwakadai se distillation nekugadzirisa. Semuenzaniso, muindasitiri yepetrochemical, toluene inowanzoshandiswa sechikafu chekugadzirwa kwemakemikari akakosha akadai sebenzene, methanol uye xylene. Nekudzora tembiricha mu reactor kuitira kuti toluene inyunguruke uye inonyunguduka mune yakakodzera tembiricha renji, kusarudza uye goho rekuita kunogona kuvandudzwa.
Kuziva nzvimbo yekubikira ye toluene kwakakoshawo pakuchengetedza kwayo kwakachengeteka uye kutakura. Nemhaka yokuti toluene inoputika uye inopisa, inoda kuchengetwa munzvimbo yakadzika-kupisa panguva yekuchengetedza, uye kusangana neoxidising agents nezvimwe zvinhu zvinokuvadza zvinofanira kudziviswa kudzivirira kuputika kana njodzi dzemoto.
Summary
Toluene sechinhu chakakosha chemakemikari mbishi, iyo yekubikira ye toluene ndiyo yakakosha parameter mukushandiswa kwayo kwemaindasitiri. Nekuwana nzwisiso yakadzama yenzvimbo yekubikira ye toluene uye zvinofurira zvinhu, maitiro ayo mukugadzira maitiro anogona kubatwa zvirinani uye maitiro akakodzera anogona kuvandudzwa kuitira kuvandudza kugona kwekugadzira nekuchengetedza.
