Konurehu tāpia

E karangatia e Mariao, me hākawa o te waikawa ahetiki acetates. Kei te nuinga whakamahia ratou rite te waiwhakaū, me e kua whakaritea nga waikano i runga i te muka. I roto i ngā, pāhare pāporo tāpia (ingoa nahanaha i roto i te reo Ingarihi - tāpia pāhare pāporo, ōrite - tote pāhare pāporo) ko te tote pāhare pāporo o waikawameha ahetiki, kua te CH3COOK tātai matū. He rite ki te 98,15 g / mol papatipu titiwha.

I raro i ngā āhuatanga noa te tāpia pāhare pāporo ko te tioata paura ma e he hygroscopic, na horahia te rangi. Ko tōna kiato Ko 1,57 g / cm³. Ko ngā wairewa te tote i roto i te wai: 100 ml memeha paku neke atu i te 200 g o te tote i te 20 ° C, me 492 go o - i 62 ° C. Ko ngāwari wairewa i roto i te pāhare pāporo tāpia waipiro (methanol me ewaro) me i te haukini, he rewakore i roto i te Etera, me te hauwaiwaro. Ko te pāmahana o te whāwehe o pāhare pāporo tāpia me 292 ° C.

konurehu tāpia Mateuteu te tauhohe i taua pūhui taketake pērā i te konurehu waihā (KOH) ranei konurehu pākawa waro (K2CO3) ki te waikawa ahetiki hua tauhohe neutralization: KOH + CH3COOH → CO2 + CH3COOK + H2O ranei utu rua: K2CO3 + CH3COOH → CO2 + CH3COOK + H2O . Hoki konganuku e tu ana i roto i te raupapa iahiko mahue o hauwai, hei tauira, te konurehu konupora ranei, āhuatanga e tauhohenga ki waikawa oxidizing-kore. Taua waikawa ngā waikawameha ahetiki. A, no te pāhekoheko reira, hei tauira, konupora, whiwhi tāpia konupora te: Mg + 2CH3COOH → Mg (CH3COO) 2 + H2. Ko tenei tikanga e kore whakamahi mahi mo te faaineineraa o te konupora pāhare pāporo ranei tote o te waikawa ahetiki. I roto i te āhua free, e kore e enei konganuku tīariari i roto i te natura, a pāhare pāporo no o ratou tauhohenga tauhohe ngā ki te wai, me te oxidized e hāora kōhauhau. Otiia ko reira he whakarewa tino utu me te te whakamahia noa iti pinepine i te konutai.

whakamahia pāhare pāporo tāpia rite ki GOST 5820-78 kei roto i te hanga o waerau silicon waro (silicones - ahunga i roto i te ahumahi o ngā hua polymer nui, me te fafau). Kei te whakamahia hoki konurehu tāpia rite te whākōkī i roto i te hanga o polyurethanes. Ko tētahi atu wāhi nui o te tono o te pāhare pāporo tāpia - tona whakamahi rite te deicer. he maha o painga tenei kaiwhakahohe kua (ko reira iti pukuriri i roto i te faatura o te oneone), me te reira whakakapi i pūhaumāota konupora konupūmā ranei i te tukatuka o runways i taunga rererangi, me ona pānga ha'iriiri i runga i te konganuku he iti iho i te pūhau. he kinokore ki te nuinga o papa, tae atu raima, whakarewa, rakau, hake, pangakuti me te otaota konurehu tāpia. Ko mai te mea teitei ake i taua o te pūhau tona utu, maha meinga te whakamutunga, ahakoa te maumaui e taiao, me te nui haere te kākahu o te taputapu. I tua atu, pāhare pāporo tāpia, ko te whai hua ahi-whakapoko me te whakamahia ki te tinei ahi. Kei te whakamahia te reira no te tupohe i te hinu.

whakamahia pāhare pāporo tāpia te kore anake i roto i ngā tautuhinga ahumahi engari ano i roto i te rongoa me te ahumahi kai (whai hua E261 rokiroki, hangaia kia rite ki GOST 5820-78). No te whakarite, tetahi tote o te waikawa - konupūmā tāpia - tono e kore e ahumahi. Kei te whiwhi te reira i anake i roto i te tikanga taiwhanga i te pānga o te waikawameha ahetiki i runga i te konupūmā pākawa waro. tonu te tauhohenga te tae noa oti whakakorenga o te hauhā: CaC3 + 2CH3COOH → CO2 ↑ + (CH3COO) 2Ca + H2O. Whakamahia (CH3COO) 2Ca anake rite te tāpiri kai E263 no (rite CH3COOK) ko te rokiroki whai hua.

A, no te whakakapinga therapy mo te maimoatanga o te ketoacidosis mate huka whakamahia pāhare pāporo tāpia. Ka taea te te ārai te hua ketoatsidoticheskaya coma mate huka, e kia tupu rite ki te hua o te acidosis pūkoro (pH heke) meinga e disorders pūkoro e tika ana ki te hē taiki pancreatic (taiāki). nohanga High o toto kūhuka i me te ketone tinana e he tino teitei ake i te ketoatsidoticheskaya uara whaiaroaro arata'i ki pōroa huka. konurehu tāpia, whakamahia te rite te tāpiri kai, pera me ahei o te whakaiti i te taumata o te kawatanga ki hanehane warorua. Hoki tenei take, kua whakamahia te reira ki te hamani tūroro ki te tātaritanga o te momo tuatahi o te mate huka.
