Tikanga Whakahāora Propylene o te Waikawa Oxalic
E rua ngā taahiraa o tēnei tukanga whakapūngao: te whakapūngao i te propylene ki te waikawa hauota hei huri i te waikawa lactic α-nitro, kātahi ka whakapūngao anō kia puta ai te waikawa oxalic. Mā te tikanga whakapūngao propylene ka puta te waikawa oxalic dihydrate taumata-ahumahi, me te hua katoa neke atu i te 90% i runga i te propylene. Ahakoa he nui te hua o tēnei tikanga, me aro nui ki te ārai i te pahūtanga i te wā o te tukanga whakaputa, inā koa i te wā o te tukanga whakapūngao pāmahana teitei.
