Ukuchazwa kwe-Methanol: Izici, ukukalwa nezici ezithinta
Ukubuka konke kwe-methanol density
I-Methanol (ifomula yamakhemikhali: I-CH₃OH) izinto ezibalulekile ezifuywayo zamakhemikhali, futhi ubuningi bayo buyipharamitha ebalulekile yomzimba ekala ubudlelwano bayo obunamandla. Ulwazi nokuqonda kobuningi be-methanol kubalulekile ekukhiqizeni kwezimboni, izinhlelo zokusebenza zamakhemikhali nasezokuthutha. Imvamisa, ukuhlukunyezwa kuyimpahla engokwemvelo yento futhi kuhlobene kakhulu nezimo ezifana nokushisa nengcindezi. Kulesi sihloko, sizoxoxa ngokuningiliziwe izakhiwo ze-methanol density, izindlela zayo zokulinganisa kanye nezici ezithinta lokho, ukukusiza uqonde kangcono le phapha elibalulekile.
Izakhiwo eziyisisekelo ze-methanol density
Ubukhulu be-methanol buvame ukuvezwa ngokuya ngevolumu ngeyunithi ngayinye ye-methanol, futhi ezimeni ezijwayelekile (ie, 20 ° C kanye ne-1 ATM), ubuningi be-methanol bucishe bangu-0.7918 g / cm³ g / cm³. Kubalulekile ukuqaphela ukuthi leli nani liyahlukahluka ngokushisa nokucindezela, ngakho-ke ubukhulu buhluka kancane ngaphansi kwezimo ezihlukile zokusebenza. Ukuqonda izakhiwo eziyisisekelo ze-methanol density kusiza ekuphatheni okunembile kokuphathwa kwemitha nokuphendula ngezindlela zamakhemikhali.
Izici ezithinta i-methanol density
Umphumela wokushisa ku-methanol density
Ukushisa kungenye yezinto ezibaluleke kakhulu ezithinta ubuntu be-methanol. Njengoba izinga lokushisa lenyuka, amandla e-kinetic wama-molekyuli we-methanol anda futhi ibanga phakathi kwama-molecule anda, okuholela ekwehliseni kwabantu. Isibonelo, emazingeni okushisa asekamelweni (i-20 ° C), i-methanol inobude be-0.7918 g / cm³, okuncipha kuye cishe ngo-0.762 g / cm³ lapho izinga lokushisa lenyuka laya ku-60 ° C. Lokhu kuncika kokushisa kumele kubhekwe kwizicelo ezisebenzayo, ikakhulukazi lapho kuhileleka khona ukusebenza okuphezulu kokushisa noma lapho ivolumu ye-methanol idinga kukalwa ngokunembe.
Umphumela Wengcindezi ku-Methanol Density
Yize umphumela wengcindezi ekubuthakathaka koketshezi imvamisa emincane, endaweni ephezulu kakhulu le nkinga ayinakunakwa. Ingcindezi eyandayo iphoqa amabanga phakathi kwama-molecule ukuncipha, ngaleyo ndlela yandisa kancane ubuntu be-methanol. Ngoketshezi njenge-methanol, izinguquko ekunciphiseni ngenxa yokucindezela zivame ukubizwa kancane kunokushintshwa kwezinga lokushisa. Ngakho-ke, umphumela wengcindezi ebunzimeni be-methanol bangabhekwa njengesekondatho ngaphansi kwezimo ezisebenzayo ezisebenzayo, kepha le nto isadinga ukucatshangelwa emishini yamakhemikhali ephezulu.
Izindlela zokulinganisa ze-methanol density
Indlela yokulinganisa kwelebhu
Elabhorethri, inqwaba ye-methanol ivame ukukalwa kusetshenziswa ibhodlela elithile lokudonsela phansi noma i-densitometer. Indlela ethile yamabhodlela adonsela phansi iyindlela yokulinganisa ye-Classical density, lapho ubuntu bubalwa ngokulinganisa isisindo sebhodlela elithile lokudonsela phansi eligcwele uketshezi. I-densitometer iyithuluzi elilinganisa ngokuqondile ubungako boketshezi futhi inquma ubungako boketshezi ngomgomo we-buoyancy we-floats. Zombili lezi zindlela zinezinzuzo zazo nokubi, okwakudala kunembe kakhulu kepha kuyinkimbinkimbi ukusebenza, eyokugcina kulula ukusebenza kepha kudinga ukubiza okukhulu kwensimbi.
Ukulinganiswa Kwezimboni On-Line
Ekukhiqizweni kwezimboni, ukubhekwa kwesikhathi sangempela sokuqina kwe-methanol kubalulekile ukuze kulawulwe inqubo. Amadivayisi wokulinganisa we-On-line density desity afaka phakathi ama-densitometers avelelayo ama-densitometers kanye nama-densitometers e-ultrasonic. Ukudlidliza ama-desitometers ama-tube anqume ukulinganisa ubukhulu ngokulinganisa imvamisa evumayo yoketshezi ngaphakathi kwe-tube evuthayo, ngenkathi ama-densitometers e-ultrasonic athola ubuningi obuvela ku-velocity amagagasi e-ultrasonic ahamba ngoketshezi. Lawa madivayisi ahlinzeka ngedatha yesikhathi sangempela ngesikhathi sokukhiqiza ukuze aqinisekise ukuthi izimo zokusebenza ziphakathi kwemingcele efanelekile.
I-Methanol Density embonini yamakhemikhali
Ukuzimisela okunembile nokulawulwa kwe-methanol density kunezinhlobonhlobo zezicelo embonini yamakhemikhali. Isibonelo, e-Reaction Engineering, ukuhlukunyezwa yipharamitha esemqoka e-accounting ne-accounting energy. Lapho ugcina futhi uhambisa i-methanol, idatha yobunzima ingasiza ekutholeni amandla okugcwalisa amathangi okugcina kanye nokulayishwa kwezimoto zokuhamba. Idatha ye-density nayo ingasetshenziswa ukuqapha ubumsulwa be-methanol, njengoba ubukhona bokungcola buvame ukuholela ekuhlukahlukaneni okungafanele ekubunjweni.
Ukubeka kafushane
I-Methanol Density iyipharamitha esemqoka embonini yamakhemikhali, ethinta izici eziningana zokusebenza nokwakhiwa. Ngokuqonda izakhiwo zayo, izindlela zokulinganisa kanye nezinto ezinomthelela, abasebenza embonini yamakhemikhali bayakwazi ukulawula kangcono inqubo yokukhiqiza, basebenzise ukusetshenziswa kwezinsizakusebenza futhi baqinisekisa ukuphepha kokukhiqiza kanye nokusebenza kahle. Ukwehlukanisa ukuqonda nokusetshenziswa kwe-methanol density ngaphansi kwezimo ezahlukahlukene kuyindlela ebalulekile yokwenza ngcono imisebenzi yezimboni.
