I-methylene chloride, i-organic compound kunye ne-chemical formula CH2Cl2, ngulwelo olungenambala obala kunye nephunga elimnandi elifana ne-ether.Inyibilika kancinane emanzini, ethanol nakwi-ether.Ngaphantsi kweemeko eziqhelekileyo, i-solvent engatshiyo enendawo ephantsi yokubilisa.Xa umphunga wayo uba nguxinzelelo oluphezulu kumoya wobushushu obuphezulu, uya kuvelisa irhasi exubeneyo evuthayo etshisayo, eqhele ukusetyenziselwa indawo enokutsha yepetroleum ether, ether, njl.
Iinkcazelo ngeempawu:Unyului-methylene chlorideakanalo ukhanyiso.Izinyibilikisi eziqulethe umthamo olinganayo we-dichloromethane kunye nepetroli, i-solvent naphtha okanye i-toluene ayinakutsha.Nangona kunjalo, xa i-dichloromethane ixutywe ne-acetone okanye i-methyl Chemicalbook alcohol liquid in 10: 1 ratio mixing, umxube une-flash point, umphunga kunye nomoya ukwenza umxube oqhumayo, umda wokuqhuma 6.2% ~ 15.0% (umthamo).
ISICELO:
1. Isetyenziselwa i-grain fumigation kunye nefriji yefriji ephantsi yoxinzelelo kunye neyunithi yomoya.
I-2, isetyenziswe njenge-solvent, i-extractant, i-agent ye-mutagenic.
I-3, esetyenziswa kwishishini lombane.Ngokuqhelekileyo isetyenziswe njenge-arhente yokucoca ukususa ioli.
I-4, Isetyenziswe njenge-anesthetic yendawo yamazinyo, i-refrigerant, i-ejenti yokucima umlilo, i-metal surface coating coating kunye ne-agent ye-degreasing.
I-5, Isetyenziswe njengendawo ephakathi kwi-organic synthesis.
Indlela yokulungiselela:
1. Inkqubo yegesi yendalo yekhlorine Irhasi yendalo idibana negesi yeklorin.Emva kokuba i-hydrochloric acid eveliswa yi-hydrogen chloride ifunnwe ngamanzi, i-residual trace hydrogen chloride isuswa nge-lye, kwaye imveliso egqityiweyo ifunyenwe ngokumisa, ukunyanzeliswa, ukuxinzelela kunye ne-distillation.
2. I-Chloromethane kunye ne-chloromethane yasabela ngegesi ye-chlorine engaphantsi kwe-4000kW ukukhanya ukuvelisa i-dichloromethane, eyagqitywa ngokuhlamba kwe-alkali, ukunyanzeliswa, ukudibanisa, ukomisa kunye nokulungiswa.I-byproduct ephambili yi-trichloromethane.
Ukhuseleko:
1.Imiqathango yokusebenza:Kuphephe ukuwisa inkungu ngexesha lokusebenza, kwaye unxibe izixhobo ezifanelekileyo zokuzikhusela.Kuphephe ukukhupha umphunga kunye namathontsi enkungu emoyeni wendawo yokusebenza.Sebenza kwindawo ethile enomoya omhle kwaye uthathe inani elincinci.Izixhobo zokusabela ngokungxamisekileyo kufuneka zibekhona ngamaxesha onke ukulwa nomlilo kunye nokujongana nokuchitheka.Izikhongozeli ezingenanto zokugcina zisenokuqulatha iintsalela eziyingozi.Sukusebenza kwindawo yewelding, idangatye, okanye indawo eshushu.
2.Izilumkiso zokugcina:Gcina kwindawo epholileyo, eyomileyo, kwindawo engenamoya ngaphandle kwelanga elithe ngqo.Gcina kude nomthombo wobushushu, ilangatye kunye nokungahambelani okufana ne-oxidant eyomeleleyo, i-asidi eqinile kunye ne-nitric acid.Gcina kwisikhongozeli esibhalwe ngokufanelekileyo.Izikhongozeli ezingasetyenziswanga kunye namagubu angenanto kufuneka zigqunywe ngokuqinileyo.Kuphephe umonakalo kwisikhongozeli kwaye uhlole itanki rhoqo iziphene ezifana nokuqhekeka okanye ukuchitheka.Izikhongozeli zifakwe i-galvanized okanye i-Phenolic resin ukunciphisa ukubola kwe-methylene chloride.Ugcino olulinganiselweyo.Thumela iimpawu ezilumkisayo apho kufanelekileyo.Indawo yokugcina kufuneka ihlulwe kwindawo yokusebenza yabasebenzi kwaye ithintelwe ukufikelela kwindawo.Sebenzisa imibhobho yeplastiki eyenzelwe ukusetyenziswa nezinto ezikhupha izinto eziyityhefu.Isixhobo sinokwakha umbane ongatshintshiyo onokudala ukutsha.Gcina kwindawo epholileyo, eyomileyo, nengena umoya kakuhle kude nelanga elithe ngqo.
3.Ukupakishwa kunye nokuthutha:Sebenzisa imiphanda yentsimbi ukuba ivalwe, 250kg umphanda, itanki kaloliwe, imoto inokuthuthwa.Kufuneka igcinwe kwindawo ebandayo, emnyama, eyomileyo, kwindawo engenamoya, qaphela ukufuma.
