āhuatanga matū

taea ki te whai wāhi i roto i te katoa o nga tauhohe i he āhuatanga o te raupapa huirua o aldehydes tīmeka Formaldehyde ko. Tae atu ki te nucleophiles. Kei te whai pānga hoki te reira ki te whakaiti āpiha. Ko te nuinga e tika ana ki te meka i te formaldehyde he kiato irahiko iti i runga i te ngota waro tenei. Ngā mihi ki tenei āhuatanga o te hanganga reira he tino ngāwari ki te tomo ki tauhohe matū ki ara nga nucleophiles tino ngoikore. E whakamārama ana tēnei i te meka e i roto i te hāparo-tahi formic waiwai kitea i roto i te āhua hydrated.

production tangohanga

Tenei mea ko te tātai tino ohie. rite tenei hāparo-tahi Formic i te reo matū titiro: HCHO. Ko te tikanga ahumahi matua o tona production - ko te hāora o te waihā mewaro. kawea ana tēnei tauhohenga i roto i te whakamahi i te whakakōkī hiriwa. Temperature e hiahiatia ana - 650 nekehanga. puta waihā mewaro piti hāora i te pēhanga kōhauhau.

Ko kē whakamahia rawa te wa roa te nga wahi katoa tenei tukanga. Kei te pai te taukei reira. Tata 80% formaldehyde whiwhi i roto i te tauhohe oxidizing o waihā mewaro. Heoi, e kore te mea anake te ara tenei. He tata whakawhanakehia reira he tikanga noa atu whaihua. Kei te hāngai te reira i runga i te whakamahi o kaiwhakakökï rino-molybdenum. I roto i tenei take iti te taumata pāmahana e hiahiatia ana te ki te 300 nekehanga, me te tata haurua.

Hoki mohiotia ko tetahi tukanga ahumahi - te piti hāora o te mewaro. I roto i te whakautu ki tenei tātai kaua ohie: whiwhi hāparo-tahi formic te i te pēhanga o 1-2 MPa i 450 nekehanga. Ko te whakakōkī tangohia Phosphate konumohe.

tono
