1.Iyini i-DMSO?
I-Dimethylsulfoxide, i-DMSO ngamafuphi, iyinhlanganisela yezinto eziphilayo enezici eziyingqayizivele. Isuka ekuphenduleni kwamakhemikhali e-methanol ne-sulphur dioxide futhi itholakala nge-dehydrogenation. Ngaphansi kokulawulwa kwekhwalithi okuqinile, i-DMSO isetshenziswa kabanzi emikhakheni eminingi, okuhlanganisa amakhemikhali, imithi, ezolimo, njll.
Izakhiwo zomzimba ze-dimethyl sulfoxide?
I-Dimethyl sulfoxide (DMSO) iyinhlanganisela ephilayo equkethe isulfure enefomula ye-molecular C2H6OS. Iwuketshezi olusobala olungenambala nolungenaphunga ezingeni lokushisa elilingana negumbi. Iwuketshezi oluyi-hygroscopic futhi oluvuthayo. Inezici ze-polarity ephezulu, indawo yokubilisa ephezulu, ukuzinza okuhle kwe-thermal, i-aprotic kanye ne-miscible ngamanzi. Ingancibilika ezintweni eziningi eziphilayo njenge-ethanol, i-propanol, i-benzene ne-chloroform, futhi yaziwa ngokuthi "i-solvent yonke indawo". Ukushisa phambi kwe-asidi kuzokhiqiza amanani amancane e-methyl mercaptan, i-formaldehyde, i-dimethyl sulfide, i-methanesulfonic acid nezinye izinhlanganisela. Inesimo sokubola emazingeni okushisa aphezulu, isabela ngobudlova ne-chlorine, futhi isha emoyeni ngelangabi eliluhlaza okwesibhakabhaka. Ingasetshenziswa njenge-solvent ephilayo, i-reaction medium kanye ne-organic synthesis intermediate. Ingasetshenziswa futhi njengesinyibilikisi sokudaya, isikhiphi sikadayi, isithwali sokudaya semicu yokwenziwa, kanye nesinqamuleli sokubuyisa i-acetylene ne-sulphur dioxide.
Iyini imisebenzi kanye nemiphumela ye-DMSO?
Emkhakheni wamakhemikhali, i-DMSO idlala indima ebalulekile. Kuyi-solvent enhle kakhulu engasetshenziswa ukuncibilikisa izinhlanganisela eziningi ze-organic ukuze kube lula ukusabela kwamakhemikhali. Ngaphezu kwalokho, i-DMSO futhi ine-antioxidant, anti-aging, kanye nemiphumela ekhuthaza umzimba. Kuyi-scavenger yamahhala enamandla evikela amaseli emonakalweni we-oxidative. Ngesikhathi esifanayo, i-DMSO ingashukumisa umzimba weseli, ikhuthaze ukukhiqizwa kwamandla, futhi ithuthukise ubungqabavu bomzimba.
Akukhona lokho kuphela, i-DMSO futhi inemiphumela esobala yokulwa nokukhathala. Ucwaningo lubonisa ukuthi ukusebenzisa i-DMSO ngaphambi noma ngesikhathi sokuzivocavoca kungasiza abasubathi banciphise ukukhathala futhi bathuthukise ukusebenza. Imisipha ijwayele ukukhathala kanye nokulimala ngesikhathi sokuqeqeshwa okunamandla noma ukuvivinya umzimba isikhathi eside. I-DMSO ingavikela izicubu ekulimaleni kwama-radical mahhala kuyilapho ikhuthaza ukululama kwemisipha, ngaleyo ndlela ikhulule ukukhathala ngokuphumelelayo.
Indlela yokugcina
1. Lo mkhiqizo kufanele uvalwe futhi ugcinwe endaweni epholile, eyomile kude nokukhanya.
2. Lo mkhiqizo uhlanganiswe emiphongolweni ye-aluminium, imiphongolo yepulasitiki noma amabhodlela engilazi. Gcina endaweni epholile, engenamoya neyomile, futhi ugcine futhi uthuthe ngokwemithethonqubo yezinto ezivuthayo nezinobuthi.
