Suuf la safeeyey—furitaan—alkaliyeyn—ka-saaris—ka-saaris—ka-saaris—ka-saaris—dhaqid—ka-saaris, qallajin—jarid—xirid—furitaan suuf ah oo dhammaystiran: suufka la safeeyey ayaa la furay si looga saaro birta, ka dibna la shiido. Suufka la safeeyey ee la shiiday wuxuu ku jiraa qaab budo ah, cabbirka walaxdiisuna waa 80 mesh iyo gudbinta waa 100%. Haddii kale, way fududahay in la isku daro inta lagu jiro habka falcelinta oo la yareeyo waxtarka etherification.
Alkalasaarid: Ku dar suufka budada ah ee la safeeyey ka dib marka la furo dareere aan firfircoonayn, oo ku dhaqaaji alkali iyo biyo jilicsan si uu u bararo shabagga suufka la safeeyey, kaas oo ku habboon gelinta molecules-ka wakiilka etherifying, wuxuuna hagaajiyaa isku-dhafka falgalka etherification. Alkaliga loo isticmaalo alkalasaariddu waa hydroxide bir ah ama saldhig dabiici ah. Qadarka alkali ee lagu daray (cuf ahaan, isla kan hoose) waa 0.1-0.6 jeer ka badan suufka la safeeyey, xaddiga biyaha jilicsanna waa 0.3-1.0 jeer ka badan suufka la safeeyey; dareeraha aan firfircoonayn waa isku-darka aalkolada iyo hydrocarbon, xaddiga dareeraha aan firfircoonayn ee lagu darayna waa suuf la safeeyey. 7-15 jeer: dareeraha aan firfircoonayn sidoo kale wuxuu noqon karaa aalkolo leh 3-5 atamka kaarboon (sida khamriga, propanol), acetone. Waxa kale oo uu noqon karaa hydrocarbons aliphatic iyo hydrocarbons udgoon; heerkulka waa in lagu xakameeyaa 0-35°C inta lagu jiro alkalasaarid; waqtiga alkalasaariddu waa qiyaastii 1 saac. Hagaajinta heerkulka iyo waqtiga waxaa lagu go'aamin karaa iyadoo loo eegayo shuruudaha agabka iyo badeecada.
Kala-soocidda: Ka dib daaweynta alkalization-ka, xaaladaha faakiyuumka, kala-soocidda waxaa lagu sameeyaa iyadoo lagu darayo wakiil ka-soocidda, wakiilka ka-soocidda waa propylene oxide. Si loo yareeyo isticmaalka wakiilka ka-soocidda, habka kala-soocidda, wakiilka ka-soocidda waxaa lagu daraa laba jeer, xaddiga ku-darka koowaad waa 1-3.5 jeer ka badan suufka la safeeyey, wadarta guud ee labada lagu darayna waa 1.5-4 jeer ka badan suufka la safeeyey. Ka dib marka aad ku darto wakiilka ka-soocidda markii ugu horreysay, ku walaaq heerkul ah ≤30°C muddo 45 daqiiqo ah-90 daqiiqo, ka dibna ku kululee ilaa 50-100°C si aad u kala-soocidda, waqtigu waa 1-5 saacadood, ka dibna ku qabooji ilaa ≤30°C. Ku dar Jing ka-soocidda markii labaad oo walaaq, wakhtiga karinta waa 30-120 daqiiqo, ka dibna ku kululee ilaa ?? ? Samee etherification, waqtigu waa 1-4 saacadood, waqtigan, suufka la safeeyey iyo wakiilka etherifying ayaa si buuxda uga falceliya soo saarista H-HPC.
Burburinta iyo baakadaynta: badeecada la qalajiyey ee ikhtiraacan hadda jirta waa la miiray oo la shaandheeyaa. Cabbirka walxaha ee badeecada la miiray oo la shaandheeyey ee ikhtiraacan hadda jirta waa 40 mesh halka gudbinta ay tahay 10096, ama sida waafaqsan baahiyaha isticmaalaha. Kadibna ka soo saar warshadda.
