Ukuvula i-cotton-father-i-althering-ukwahlula-hlula-ukwahlula-hlula-hlula, ukuvula-ukusoma-ukupakisha i-cotton ekupakisheni: Ikotoni ecocekileyo ivuliwe ukususa i-iron, emva koko ikhutshelwe. Ikotoni ecocekileyo ikwimo yepowder ikwimo yomgubo, kwaye ubungakanani bayo buyi-80 Mesh kunye ne-Districtation yi-100%. Ngaphandle koko, kulula ukuphatha kunye ngexesha lokuphendula kunye nokunciphisa ukusebenza kakuhle kowaso.
I-Alkalization: Yongeza i-cotton ecocekileyo emva kokuvulelwa kwi-intert ye-intert, kwaye isebenze nge-alkali kunye ne-Alkali kunye ne-intermating ye-cotton, kwaye iphucule ukungena kwearhente ye-erhente yokuphendula . I-alkali esetyenziswa kwi-alkalization yi-hydroxide yensimbi okanye isiseko sezinto eziphilayo. Isixa se-alkali esongeziweyo (ngobunzima, esingezantsi) sisi-0.1-0.6 amaxesha ekotoni ecocekileyo, kunye nenani lamanzi athambileyo yi-cotton yomqhaphu; I-Inert ye-Instevent ngumxube wotywala kunye ne-hydrocarbon, kunye nenani le-intert ye-Inict yongezwa yikotoni ecocekileyo. Amaxesha angama-7 ukuya kweli-15: I-Inert ye-InEtven inakho ukuba yi-aton ye-carbon ene-Atoni (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 zezinto ezibonakalayo kunye nemveliso.
Isiqinisekiso: Emva konyango lwe-alkalition, phantsi kweemeko ze-vacuum, i-ethe therhemu yenziwa ngokongeza iarhente eyaziwayo, kwaye iarhente ye-estide i-proplene oxide. Ukwenzela ukunciphisa ukusetyenziswa kwearhente yokukhuthaza, kwinkqubo yokuthengisa, iarhente ye-ethermise yongezwa ngamaxesha amabini, isixa sodibaniso sokuqala sisiqingatha sekotoni ehlaziyiweyo ngamaxesha ayi-1.5-4 ayo yekotoni ehlaziyiweyo. amaxesha. Emva kongeza iarhente yokuqalisa okokuqala, ivuse kwiqondo lobushushu le-≤ 300 ° C ukuba i-45min-90min-90min, emva koko i-SURD ukuya kwi-AREUTION ° C, yongeza i-etherised hing okwesibini kunye nokukhuthaza, ixesha elitshatileyo lingama-300min, emva koko ubushushu buye? ? ? Yenza i-ether, ixesha yi-1-4h, ngeli xesha, i-cotton yecotton kunye nearhente yokuphucula i-esser iphendule ngokupheleleyo ukuvelisa i-H-HPC.
Ukucofa kunye nokupakisha: imveliso eyomileyo yendawo yokuyilwa yangoku ikhutshelwa kwaye ihleliwe. Ubungakanani bentsalela yemveliso etyhidiweyo kunye ne-Direen of the and i-40 mesh kunye ne-Deritrating yi-10096, okanye ngokokudinga umsebenzisi. Emva koko ukupakishe ngaphandle komzi-mveliso.
Ixesha lokuposa: I-Oct-13 ukuya ku-522
