Iimveliso
99.5% DPG Dipropylene Glycol for Perfume Garde CAS No 25265-71-8
Ingcaciso yeMveliso
I-Dipropylene glycol ifumana ukusetyenziswa okuninzi njenge-plasticizer, i-intermediate kwi-industrial reaction reaction, njenge-polymerization initiator okanye i-monomer, kunye ne-solvent. Ubuthi bayo obuphantsi kunye neempawu ze-solvent zenza ukuba ibe yinto efanelekileyo yokongeza iziqholo kunye neemveliso zokunakekelwa kwesikhumba kunye neenwele. Ikwasisithako esiqhelekileyo kulwelo lwenkungu yorhwebo, olusetyenziswa koomatshini benkungu kushishino lokuzonwabisa.

Isicelo
| Isetyenziswa njenge-nitrate ye-fiber solvent kwaye iphakathi kwi-organic synthesis |
I-1) I-Dipropylene glycol yeyona nto ifanelekileyo yokunyibilikisa kwizinto ezininzi zokuvumba kunye nezithambiso. Le mveliso eluhlaza inamanzi agqwesileyo, i-oyile kunye ne-hydrocarbon co-solubility kwaye inevumba elimnandi, ukucaphuka okuncinci kwesikhumba, ubuthi obuphantsi, ukuhanjiswa okufanayo kwee-isomers kunye nomgangatho ogqwesileyo.
2) Ingasetyenziswa njenge-arhente yokudibanisa kunye ne-ejenti yokuthambisa kwizicelo ezininzi ezahlukeneyo zokuthambisa. Kwi-perfumery, i-dipropylene glycol isetyenziswe ngaphezu kwe-50%; ngelixa kwezinye iinkqubo, idipropylene glycol isetyenziswa ngokubanzi ngaphantsi kwe-10% (w/w). Ezinye izicelo zemveliso yeChemicalbook ethile zibandakanya: iinwele ezigobileyo, izicoci zolusu (iikhrimu ezibandayo, iijeli zeshawa, ukuhlamba umzimba kunye nokuthambisa ulusu) izidevundisi, ubuso, isandla kunye neemveliso zokhathalelo lwesikhumba somzimba, iimveliso zokhathalelo lwesikhumba ezithambisayo kunye neziqholo zomlomo.
I-3) Inokuthi ithathe indawo kwii-resin ezingaxutywanga kunye ne-resins egcweleyo. Iireyini ezizivelisayo zinokuthamba okuphezulu, ukumelana nokuqhekeka kunye nokumelana nemozulu. (4) Inokusetyenziswa kwakhona njenge-cellulose acetate; i-cellulose nitrate; ivanishi yegum yezinambuzane; i-solvent kwioli ye-castor; kunye neplasticizer, fumigant, kunye nesicoci sokwenziwa.
Inzuzo
Umgangatho wemveliso, ubungakanani obaneleyo, unikezelo olusebenzayo, umgangatho ophezulu wenkonzo Inenzuzo ngaphezu kwe-amine efanayo, i-ethanolamine, ekubeni i-concentration ephezulu ingasetyenziselwa ukubola okufanayo. Oku kuvumela abasulungeki ukuba bakhuhle ihydrogen sulfide ngesantya esisezantsi se-amine esijikelezayo sisebenzisa amandla angaphantsi ngokubanzi.
