K'hothone e hloekisitsoeng-ho bula-alkalizing-etherifying-neutralizing-ho arohana-ho hlatsoa-ho arola, ho omisa-pulverizing-ho paka-ho qeta ho bula k'hothone: k'hothone e hloekisitsoeng e buloa ho tlosa tšepe, ebe e phunya. K'hothone e hloekisitsoeng e hloekisitsoeng e ka sebopeho sa phofo, 'me boholo ba eona ke 80 mesh mme phetisetso ke 100%. Ho seng joalo, ho bonolo ho agglomerate hammoho nakong ea ts'ebetso ea karabelo le ho fokotsa katleho ea etherification.
Alkalization: Eketsa k'hothone e hloekisitsoeng e phofshoana ka mor'a ho bula motsoako oa inert, 'me ue sebelise ka alkali le metsi a bonolo ho ruruha lesela la k'hothone e hloekisitsoeng, e leng se loketseng ho kenella ha limolek'hule tsa etherifying agent,' me e ntlafatsa ho tšoana ha karabelo ea etherification. . Alkali e sebelisoang ho alkalization ke tšepe ea hydroxide kapa setsi sa tlhaho. Palo ea alkali e ekelitsoeng (ka boima, e tšoanang ka tlase) ke makhetlo a 0.1-0.6 a k'hothone e hloekisitsoeng, 'me boholo ba metsi a bonolo ke makhetlo a 0.3-1.0 a k'hothone e hloekisitsoeng; solvent inert ke motsoako oa joala le hydrocarbon, 'me palo ea solvent inert e kenyelletsoeng ke k'hothone e hloekisitsoeng. 7-15 linako tse ling: solvent inert e ka boela ea e-ba joala e nang le liathomo tsa carbon tse 3-5 (tse kang joala, propanol), acetone. E ka boela ea e-ba li-hydrocarbon tsa aliphatic le li-hydrocarbon tse nkhang hamonate; mocheso o lokela ho laoloa ka hare ho 0-35 ° C nakong ea alkalization; nako ea alkalization ke hoo e ka bang 1hr. Tokiso ea mocheso le nako e ka khethoa ho latela litlhoko tsa thepa le sehlahisoa.
Etherification: Ka mor'a phekolo ea alkalization, tlas'a maemo a vacuum, etherification e etsoa ka ho eketsa moemeli oa etherifying, 'me moemeli oa etherifying ke propylene oxide. E le ho fokotsa ts'ebeliso ea etherifying agent, ts'ebetsong ea etherification, moemeli oa etherifying o eketsoa ka makhetlo a mabeli, palo ea kenyelletso ea pele ke makhetlo a 1-3.5 ea k'hothone e hloekisitsoeng, le palo eohle ea litlatsetso tse peli. ke makhetlo a 1.5-4 a k'hothone e hloekisitsoeng. linako. Ka mor'a ho eketsa moemeli oa etherifying ka lekhetlo la pele, tsosa ka mocheso oa ≤30 ° C bakeng sa 45min-90min, ebe o chesa ho fihlela ho 50-100 ° C bakeng sa etherification, nako ke 1-5h, ebe o pholile ho fihlela ho ≤30. °C , Kenya etherified Jing ka lekhetlo la bobeli 'me u tsose, nako e susumetsang ke 30-120min, ebe u chesa ho fihlela? ? ? Etsa etherification, nako ke 1-4h, ka nako ena, k'hothone e hloekisitsoeng le etherifying agent e arabela ka botlalo ho hlahisa H-HPC.
Pulverization le ho paka: sehlahisoa se omisitsoeng sa boqapi ba hona joale sea siloa ebe se sefuoa. Boholo ba karoloana ea sehlahisoa se silafalitsoeng le se sefiloeng sa boqapi ba hajoale ke mesh e 40 mme phetisetso ke 10096, kapa ho latela litlhoko tsa mosebelisi. Ebe u e ntša fekthering.
