HANGANGA:
Whakaahuatanga:
Ko te dimethyl carbonate he wai mārama, kāore he tae, he kakara reka. He kikī ake i te wai, ā, he paku wairewa ki te wai. He taumaha ake ngā kohu i te hau. Whakamahia hei hanga i ētahi atu matū, hei whakarewa hoki mō tētahi kaupapa motuhake.

Whakamahinga
Ka whakamahia te dimethyl carbonate hei whakarewa i roto i te hanga matū waro, ā, e whakaarohia ana hei whakakapi mō te whakarewa pēnei i te methyl ethyl ketone, tert-butyl acetate me te parachlorobenzotrifluoride. Kei roto i tēnei hei takawaenga i roto i te whakarite i te diphenylcarbonate, e whakamahia ana hei rauemi mata matua mō te hanga o te Bisphenol-A-polycarbonate. Ka whakamahia hoki hei kaihoko methylating 'matomato' e uru ana ki te methylation o te aniline, ngā phenols me ngā waikawa carboxylic. Ka taea te whakamahi hei tāpiri wahie nā te mea he nui te ihirangi hāora. Ka kitea hoki ngā tono e pā ana ki ngā supercapacitors me ngā pākahiko lithium.
He whakakapi pai mō te dimethyl sulfate, qv, me ngā methyl halides i roto i ngā tauhohenga methylation me te phosgene, qv, i roto i ngā tauhohenga methylcarbonylation, he pai mō te taiao.
Te Tākai me te Tukunga
200KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Nō ngā taonga noa, ā, ka taea te tuku mā te moana me te rangi
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
