Intshayelelo
I-3,5-Dimethylbenzoic acid. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
-Imbonakalo: Ikristale engenambala eqinileyo;
-Inganyibiliki kancinci emanzini kwaye inyibilika ngakumbi kwizinyibilikisi zezinto eziphilayo ezinjengeethers kunye neealkoholi;
- Inevumba elimnandi.
Sebenzisa:
- I-3,5-i-Dimethylbenzoic acid yinto ebalulekileyo ephakathi kwi-organic synthesis kwaye isoloko isetyenziselwa ukuhlanganiswa kwamanye ama-organic compounds;
- Ingasetyenziselwa njengento ekrwada ye-polyester resins kunye neengubo, iiplastiki kunye nezongezo zerabha;
Indlela:
- Indlela yokulungiselela i-3,5-dimethylbenzoic acid inokufumaneka ngokuphendula kwe-benzaldehyde kunye ne-dimethyl sulfide;
- Ukusabela ngokuqhelekileyo kuqhutyelwa phantsi kweemeko ze-acidic, kunye ne-acidic catalysts ezifana ne-hydrochloric acid ingasetyenziswa;
- Emva kokuphendula, imveliso ecocekileyo ifunyenwe nge-crystallization okanye i-extraction.
Ulwazi ngoKhuseleko:
- Ikhompawundi kufuneka isetyenziswe ngokuhambelana nemigaqo yaselabhoratri efanelekileyo;
- Inokubangela ukucaphuka kwamehlo, ulusu, kunye nenkqubo yokuphefumla;
- Nxiba izixhobo zokuzikhusela, ezinje ngeglavu zelebhu kunye neglavu, kwaye uqinisekise ukungena komoya okulungileyo xa usetyenziswa;
- Gwema ukudibanisa kunye nee-oxidizing agents ezinamandla kunye ne-acids eqinile;
- Gcina yomile, itywinwe ngokuqinileyo, kwaye uphephe ukudibana nomoya, ukufuma kunye nomlilo.
Xa usebenzisa i-3,5-dimethylbenzoic acid okanye nayiphi na enye ikhemikhali, kubalulekile ukulandela ukuphathwa kakuhle kweekhemikhali kunye neendlela ezikhuselekileyo.
