Me pēhea te whakahaere i te tikanga hanga waikawa propionic mai i te hua taha o te waikawa acetic?
Waikawa Propionic i te tīmatanga i hangaia mā te whakapūkara o te huka, te māngaro rānei, mā te wehenga rānei i te wā e whakapūkara ana i te rakau, i te whakatō maroke rānei. Heoi, he uaua te ara pākia o te whakapūkara mō te hanga waikawa propionic. Ka āraihia te hanga waikawa propionic e ngā hua whakamutunga o te Propionibacteria, ka uaua ai te kohikohi i ngā kukū tiketike o te hua. Hei tāpiri, he uaua te wehenga hua, ka iti ake te whakataetae o ngā tikanga whakapūkara ki te whakataurite ki te hanga matū.
Ko te waikura tika o ngā warowaihā tētahi tikanga matua mō te whakaputa waikawa acetic. Mā te whakamahi i te naphtha māmā, te hau hinu wai, ngā alkane rānei me ngā ira kohua i raro i tētahi pāmahana hei rauemi mata, me ngā waikura konupora, cobalt, vanadium rānei hei whakakorikori, ka whakahaerehia te waikura hau āhua-wai i te 150–250°C me te 1.0–5.0 MPa hei whakaputa waikawa acetic, me ngā hua taha tae atu ki te waikawa formic me te waikawa propionic. Mō ia tana o te warowaihā māmā, 0.65 tana o te waikawa acetic, 0.06 tana o te waikawa formic, me te 0.05 tana o te waikawa propionic ka taea te whakaputa. Ka whakamahia e tēnei tukanga ngā rauemi mata iti te utu, ā, he ngāwari te rere mahi, engari ko te hanganga uaua o te ranunga tauhohenga e hiahia ana ki te whakakorenga tango me te whakakorenga azeotropic mō te wehenga me te purenga, ka hua ake he utu haumi nui.
