Te Mahi me ngā Āhuatanga：

Ngā takawaenga rongoā, e whakamahia ana hoki i roto i te hanga o te kaihoko maimoatanga muka. E whakamahia ana i roto i te rongoā hei hanga i te theophylline, te caffeine me te nificaran hydrochloride.

Ngā Tikanga Whakamahinga:

(1) ka tukuna te hau methylamine ki roto i te urea rewa, ā, ka mimitihia te hau ammonia kua tukuna, ka whakahokia mai. I muri i te whakamataotanga o te hua tauhohenga, ka tangohia atu, ka whakakōhatu anōtia.

(2) i whakaritea te hauhā waro mā te tauhohenga whakakorikori hau-totoka me te monomethylamine.

(3) te tauhohenga o te methyl isocyanate me te methylamine.

Kete me te Rokiroki

Te takai me te putea 25kg, me te kore rānei Puritia ki roto i te ipu taketake anake i roto i te wāhi hauhautanga me te hauhautanga pai. Puritia kia matara atu i ngā mea kāore e hototahi. Me āta tirotiro ngā ipu kua whakatuwheratiakua hiritia anō, ā, kua puritia kia poutū hei ārai i te turuturu. Āta karohia te wā rokiroki roa.
