Tikanga Tukatuka

He tikanga mo te whakarite i te tris(hydroxymethyl)aminomethane, e whai ake nei nga mahi whakarite:

(1) Tāpirihia te trimethylolmethane ki te wairewa wai methanol, whakamahana ki te 50-70°C me te whakaoho kia memeha, kei reira te ōwehenga papatipu-rōrahi o te trimethylolmethane ki te wairewa wai methanol he 8:3-7 i te g/ml , Te ka whakaritea te wairewa wai mewaro ma te ranu i te wai parakore me te mewaro i roto i te owehenga rōrahi o te 2:3;

(2) Taapirihia te waro whakahoahoa waro ki te otinga, ko te tauwehenga taumaha o te waro whakahohe waro ki te trimethylolmethane he 0.5-2:100, pupuri i te 45-55°C mo te 20-40 meneti, tātarihia i te wa e wera ana te Puka Maama. , ka kohia te filtrate ；

(3) Whakakotahitia te filtrate i raro i te pehanga iti i te pāmahana kukū o 70-80°C, kia puta nga tioata, kia whakamatao;

(4) I muri i te wehenga o nga tioata e te filtration momi, horoia ki te waihā tino me te maroke i te 40-60 ° C mo te 3-5 haora ki te whiwhi.

Ko te tikanga whakarite o te tris kua whakahuahia ake nei, ko te tris kua whiwhi he tino parakore, e tutuki ana i te whakaritenga o te reagent tohu mo te ma o te tris, a he pumau, he whaitake hoki te tukanga, he mea tino pai mo te hanga o nga hua puranga kirokaramu.He ngawari, he whaitake hoki te tukanga, he nui te reiti tohu tohu hua, e tika ana mo nga hiahia o te hanga ahumahi nui.
