I-cotton yokuvula-i-alkalition-i-alkulition-ukungathathi cala-yokwahlula-hlula-hlula-vala-ukutyholwa kwemveliso egqityiweyo: Ikotoni ecocekileyo ivuliwe ukususa i-iron kwaye emva koko kutyunyuzwe. Ikotoni ecocekileyo ikwimo yepowder ikwimo yomgubo, ubungakanani bentshukumo ye-80 mesh kunye nokudlulisela i-100%. Ngaphandle koko, kulula ukuvumelana kunye ngexesha lokuphendula kunye nokunciphisa ukusebenza kakuhle kowaso.
I-Alkalization: Yongeza i-cotton ecocekileyo emva kokuvulwa kwekotoni kwi-intert ye-intert, kwaye isebenzise i-alkali kunye ne-Alkali kunye ne-Alkali kunye ne-Alkali kunye ne-Alkali kunye ne-Alkali kunye ne-Alkali kunye ne-Arkali kunye ne-Agering ye-Arhente ye-Etherhesical kwaye iphucule ukufana kwe-ethermoides yokuphendula. I-alkali esetyenziselwa i-alkalization yi-hydroxide yentsimbi okanye i-alkalic alkali. Isixa se-alkali esongeziweyo (ngobunzima, esingezantsi) sisi-0.1-0.6 amaxesha e-cotton ehlaziyiweyo, isixa samanzi athambileyo ongezelelweyo yi-cotton ecocekileyo; I-Inert ye-Insert ingumxube wotywala kunye ne-hydrocarbon, kunye nenani le-intert yongezwa yi-0.3-1.0 amaxesha ekotoni ecocekileyo. Izihlandlo ezi-7 -15 zelo: I-Inert ye-InErt inakho ukuba yi-Aton ye-carbon ene-3-5 yekharbon (efana notywala, i-propanol), i-acetone. Ingakwazi ukuba nee-hydrocarbons ze-hydrocarbons kunye neebhulukhwe ze-hydrocarbons; amaqondo obushushu kufuneka alawulwe ngaphakathi kwe-0-35 ° C ngexesha lokuphulukana; Ixesha le-alkali imalunga ne-1hr. Uhlengahlengiso lobushushu kunye nexesha lungagqitywa ngokweemfuno zemveliso kunye neemveliso zemveliso.
Isiqinisekiso: Emva kwempangelo lokwahlula i-alkali, phantsi kweemeko ze-vacuum, iarhente ye-Etherise yongezwa kwi-Etherhesition, kwaye iArhente ye-Etherise i-proplenene oxide. Ukwenzela ukunciphisa ukusetyenziswa kwe-arhente ye-elekuthi, ngexesha le-Etheristition, i-Arhente ye-Etherise yongezwa kumaxesha amabini, isixa sodibaniso sokuqala sisiqingatha sekotoni emibini yi-1.5-4 yamaxesha ekotoni ecocekileyo. amaxesha. Emva kokongeza iarhente yokuthetha okokuqala, i-° i-45min-90min, emva koko iphumele ukuya kwi-1 ukuya kwi-5 ukuya kwele-5. ? ? Yenza i-ether, ixesha yi-1-4h, ngeli xesha, ikotoni ecocekileyo iphinda isebenze ngokupheleleyo nge-Arhente ye-E-Arhente ukuba ivelise i-H-HPC.
Ukutyumza kunye nokupakisha: Ukutyumza kunye nokusithelisa imveliso eyomileyo yokutshiswa kwangoku, ubungakanani bemveliso yemveliso yangoku emva kokutyumba i-10096, okanye ngokokusebenza komsebenzisi. Emva koko upakishe umzi-mveliso
IXESHA LOKUQALA: FEB-21 ukuya ku-525
