Te Matawai Whero-whero (IR) o te Waikawa Propionic
Whakamahia he ine irahiko pūwhero hei kimi. Hei tauira, hei tautuhi i te waikawa propionic me ētahi atu matū rite, tāpirihia he iti noa te tauira waikawa propionic ki runga i te pire pāhare pākawa waro, whakamahia rānei te tikanga kiriata wai hei whakarite i tētahi tauira whakamātautau e tika ana. Kātahi ka whakanohoia te tauira ki roto i te pūtau tauira o te ine irahiko pūwhero. Ka tukuna e te ine irahiko pūwhero te mārama pūwhero. Ina whiti te mārama pūwhero ki te tauira, ka mimitihia e ngā ngota tauira ngā auau motuhake o te mārama pūwhero, ka puta he nekehanga taumata pūngao wiri me te hurihanga. Ka mimitihia e ngā hononga matū rerekē ngā auau rerekē o te mārama pūwhero, ka hua ake he tihi mimiti āhua i roto i te ine irahiko pūwhero. Kei roto i te waikawa propionic ngā rōpū mahi pērā i te waikawa carboxylic, e whakaatu ana i ngā tihi mimiti āhua rite i roto i te ine irahiko pūwhero (hei tauira, ko te tihi wiri totoro o te rōpū waikawa carboxylic he tata ki te 1700 cm⁻¹). Mā te whakataurite i te ine i whiwhihia ki te ine irahiko pūwhero paerewa o te waikawa propionic e mōhiotia ana, ka taea te whakatau mēnā he waikawa propionic te tauira. Ka taea hoki te whakatau tata i te nui o te waikawa propionic i runga i te kaha o ngā tihi āhuatanga, engari ko tēnei tikanga te mea e whakamahia whānuitia ana mō te tātaritanga kounga.info@pulisichem.cn
