Ukusetshenziswa
Enye yezinzuzo eziyinhloko ze-DMC yikhono layo lokushintsha i-phosgene njenge-ejenti ye-carbonylating, ihlinzeka ngenye indlela ephephile futhi enobungani bemvelo. I-Phosgene ibeka engcupheni enkulu empilweni yabantu nasezinhlelweni zemvelo ngenxa yobuthi bayo. Ngokusebenzisa i-DMC esikhundleni se-phosgene, abakhiqizi abakwazi nje ukuthuthukisa amazinga okuphepha, kodwa futhi babambe iqhaza ekukhiqizeni okuluhlaza, okuhlanzekile.
Ngaphezu kwalokho, i-DMC ingasebenza njengebambela elihle kakhulu le-methylating agent dimethyl sulfate. I-Dimethyl sulfate iyinhlanganisela enobuthi kakhulu ebeka ingozi enkulu kubasebenzi nasendaweni ezungezile. Ukusebenzisa i-DMC njenge-ejenti ye-methylating kuqeda lezi zingozi kuyilapho kunikeza imiphumela eqhathanisekayo. Lokhu kwenza i-DMC ilungele izimboni ezikhiqiza imithi, amakhemikhali ezolimo, namanye amakhemikhali abalulekile e-methyl.
Ngaphezu kwezinzuzo ezishiwo ngenhla, i-DMC iphinde ivelele njengesixazululi sobuthi obuphansi, okuyenza ibe ukukhetha okukhangayo kwezinhlelo zokusebenza ezihlukahlukene. Ubuthi bayo obuphansi buqinisekisa indawo yokusebenza ephephile, kunciphisa ubungozi bokuchayeka kwezisebenzi kanye nabathengi ezintweni eziyingozi. Ngaphezu kwalokho, ukuncibilika okuhle kakhulu kwe-DMC nokuhambisana okubanzi nezinto ezihlukahlukene kuyenza ibe isithako esibalulekile ekwenziweni kwezithasiselo zikaphethiloli. Ukusebenzisa i-DMC njengesinyibilikisi sezithasiselo zikaphethiloli kuthuthukisa ukusebenza kahle okuphelele kokuvutha kukaphethiloli, okunciphisa ukukhishwa kwegesi futhi kuthuthukise ukusebenza kwenjini.
Sengiphetha, i-dimethyl carbonate (DMC) iyindlela eguquguqukayo futhi esimeme kumakhompiyutha wendabuko. Ukuphepha kwayo, ukunethezeka, ubuthi obuphansi nokuhambisana kwenza i-DMC ilungele uhla olubanzi lwezinhlelo zokusebenza. Ngokufaka esikhundleni se-phosgene ne-dimethyl sulfate, i-DMC inikeza inketho ephephile, eluhlaza ngaphandle kokuyekethisa ukusebenza. Kungakhathaliseki ukuthi isetshenziswa njenge-ejenti ye-carbonylating, i-methylating agent, noma isincibilikisi esinobuthi obuphansi, i-DMC iyisixazululo esithembekile sezimboni ezifuna ukuthuthukisa imikhiqizo nezinqubo kuyilapho zinciphisa umthelela wendawo.
