Kaihanga Utu Pai Waikawa Oxalic CAS：144-62-7

Waikawa Oxalic Utu Pai a te Kaihanga CAS：144-62-7 Whakaahua Matua

whakaahuatanga poto:

Ko te waikawa oxalic he waikawa dicarboxylic kaha e kitea ana i roto i te maha o ngā tipu me ngā huawhenua, ko te tikanga he tote konupūmā, he tote pāhare pākawa rānei. Ko te waikawa oxalic anake te matū e honoa tika ana ngā rōpū carboxyl e rua; nā reira ko te waikawa oxalic tētahi o ngā waikawa waro kaha rawa atu. Kāore i rite ki ētahi atu waikawa carboxylic (haunga te waikawa formic), ka tere te waikura; nā reira he mea whai hua hei whakaiti i te whakaahua, te whakama, me te tango waituhi. Ko te waikawa oxalic te tikanga ka whakaritea mā te whakamahana i te konutai formate ki te konutai hauwai hei hanga i te konutai oxalate, ka hurihia hei konupūmā oxalate ka rongoatia ki te waikawa whanariki hei whiwhi i te waikawa oxalic kore utu.
He iti noa te kukū o te waikawa oxalic i roto i te nuinga o ngā tipu me ngā kai tipu, engari he nui te kukū o te pīnihi, te chard me te pīti hei whakararuraru i te mimiti o te konupūmā kei roto i ēnei tipu.
Ka puta i roto i te tinana mā te pākia o te waikawa glyoxylic, te waikawa ascorbic rānei. Kāore e pākia engari ka tukuna ki roto i te mimi. Ka whakamahia hei matū tātari me te matū whakaiti whānui. Ko te waikawa oxalic he acaricide tūturu e whakamahia ana hei rongoā mō ngā mite varroa i roto i ngā koroni kāore he uri, he kete, he kahui rānei. Ka whakamahia te waikawa oxalic kua mimitihia e ētahi kaitiaki pī hei patu pepeke ki te mite Varroa pirinoa.

Ngā Āhuatanga Matū:He paura kore tae, kore kakara, he totoka kirikiri rānei te waikawa oxalic. Ko te āhua kore wai (COOH)2 he totoka ma, kore kakara; ko te otinga he wai kore tae.

Ngā Whakamahinga o te Waikawa Oxalic

1. Ka taea te whakamahi i te waikawa oxalic hei whakaiti me te whakama, hei whakakā mō te ahumahi tae me te tā, ā, ka whakamahia hoki ki te whakamahine i ngā konganuku onge, te hanga i ngā momo oxalate ester amide, oxalate me te tarutaru, me ētahi atu.

2. Whakamahia hei matū tātari.

3. Whakamahia hei matū taiwhanga, hei matū tātari chromatography, hei takawaenga tae me te rauemi paerewa.

4. Ko te waikawa oxalic te nuinga o te wā e whakamahia ana mō te hanga rongoā pērā i te paturopi me te borneol me te whakarewa mō te tango i te konganuku onge, te whakaiti me te tae, te tanning agent, me ētahi atu. Hei tāpiri, ka taea hoki te whakamahi i te waikawa oxalic mō te hanga i ngā momo oxalate ester, oxalate, me te oxamide me te diethyl oxalate, te sodium oxalate me te calcium oxalate te hua nui rawa atu. Ka taea hoki te whakamahi i te oxalate mō te hanga cobalt-molybdenum-alumina catalyst, te horoi i te konganuku me te māpere me te whakama i ngā kakahu.

Ngā Whakamahinga Ahuwhenua：Ko te waikawa oxalic, (COOH)2, e kiia ana ko te waikawa ethanedioic, he totoka ma, he tioata, he paku wairewa ki te wai. He matū waro tino waikura tēnei e puta noa ana, he nui te kaha ki te chelating. He tino waikawa, he paitini hoki, e whakaputaina ana e te maha o ngā tipu pēnei i te sorrel (sourwood), ngā rau o te rhubarb, te kiri o te eucalyptus me te maha o ngā pakiaka tipu. I roto i ngā pūtau me ngā kiko tipu, ka kohia te waikawa oxalic hei konutai, pāhare pāporo, konupūmā oxalate rānei, ā, ko te mea whakamutunga ka puta hei tioata. Nō reira, ka uru ngā tote o ngā waikawa oxalic ki ngā tinana o ngā kararehe me ngā tāngata, ka puta he mate pāwera, i runga i te nui o te kai. He maha ngā momo harore pēnei i a Aspergillus, Penicillium, Mucor, me ētahi lichens me ngā pokepokea ai e whakaputa ana i ngā tioata konupūmā oxalate. I te matenga o ēnei moroiti, tipu me ngā kararehe, ka tukuna ngā tote ki te oneone, ka puta he paitini. Heoi, ka whakaitihia e ngā moroiti e whakaiti ana i te oxalate, e kiia nei ko Oxalobacter formigenes, te mimiti o te oxalate i roto i ngā kararehe me ngā tāngata.

Ko te waikawa oxalic te tuatahi o te raupapa o ngā waikawa dicarboxylic. E whakamahia ana (a) hei kaiwhakamā mō ngā paru pēnei i te waikura, te mangumangu rānei, (b) i roto i te hanga kakahu me te hiako, me (c) hei monoglyceryl oxalate i roto i te hanga waipiro ally1 me te waikawa formic.
