Intshayelelo
I-methyl hydrogen azelate, ekwabizwa ngokuba yipolycarboxylate, yeyona polima iphezulu yemolekyuli ebalulekileyo. Inezi mpawu zilandelayo:
1. Iimpawu ezibonakalayo: I-methyl hydrogen azelete ayinambala okanye lulwelo olumthubi olukhanyayo, kunye nokunyibilika okulungileyo, ukunyibilika emanzini, utywala kunye nezinyibilikisi eziphilayo.
2. Iimpawu zeMichiza: i-methyl hydrogen azelate yi-ester compound enezinzo eliphezulu kunye nokuchasana kweekhemikhali. Inokuthi ifakwe i-hydrolyzed kwi-azelaic acid kunye ne-methanol.
Olona setyenziso luphambili lwe-methyl hydrogen azelate lubandakanya:
1. Ukulungiswa kwepolymer: imethyl hydrogen azelate ingenziwa ipolymer kunye nezinye iimonomers ukulungiselela iipolima eziphezulu zemolekyuli. Ezi polymers zineempawu ezintle kwaye zinokusetyenziswa kumashishini ahlukeneyo afana neengubo, iiglues, iiplastiki, iifayibha, njl.
2. I-Surfactant: i-methyl hydrogen azelete ingasetyenziswa njenge-emulsifier, i-dispersant kunye ne-wetting agent, esetyenziswa ngokubanzi kwi-cosmetics, i-detergents kunye nemveliso yokunyamekela komntu kunye nezinye iindawo.
Iindlela zokulungiselela i-methyl hydrogen azelate ikakhulu zezi zilandelayo:
1. Ukusabela kwe-transesterification: i-transesterification reaction yenziwa nge-nonyl alcohol kunye ne-methyl formate phambi kwe-acid catalyst ukufumana i-methyl hydrogen azelate.
2. Ukusabela ngokuthe ngqo kwe-esterification: i-esterification ye-nonanol kunye ne-formate phantsi kwesenzo se-asidi catalyst ukuvelisa i-methyl hydrogen azelate.
Qaphela olu lwazi lulandelayo lokhuseleko xa usebenzisa kwaye uphethe i-methyl hydrogen azelete:
1. I-methyl hydrogen azelete iyacaphukisa kwaye kufuneka ihlanjwe ngoko nangoko xa idibene nolusu kunye namehlo.
2. Kuphephe ukuphefumla umphunga wemethyl hydrogen azelate kwaye uwusebenzise kwindawo engena umoya.
3. I-methyl hydrogen i-azelate inetyhefu ephantsi, kodwa ukuvezwa kwexesha elide kunye nokukhulu kunokuba neempembelelo kwimpilo, kwaye ukubonakaliswa okugqithisileyo kufuneka kugwenywe.
4. Xa ugcina kwaye uhambisa i-methyl hydrogen azelate, yigcine kude nomlilo kunye nobushushu obuphezulu ukunqanda ingozi yokutsha kunye nogqabhuko-dubulo.
Nceda uqaphele ukuba ngaphambi kokusebenzisa i-methyl hydrogen azelate okanye nayiphi na ikhemikhali, kuya kufuneka ufunde ngononophelo kwaye ulandele iinkqubo ezifanelekileyo zokhuseleko.
