ʻŌlelo Haʻi Mua

ʻO 1,1,3■ trichloroacetone kahi mea waena koʻikoʻi i ka hana ʻana o ka waikawa folic. I kēia manawa, 1,1,3. acetone trichloropacetone, ka pōʻaiapuni hana lōʻihi (48 hola), koho maikaʻi ʻole, hua haʻahaʻa, ʻo ka ʻike o 1,1,3-trichloropacetone ma kahi o 17% wale nō, ma hope o ka unuhi ʻana i ka wai, ʻo kona ʻike he 51.9% wale nō. A kiʻekiʻe ke kumukūʻai hana, haʻahaʻa ka hoʻoponopono huahana. ʻO kēia mau mea a pau e alakaʻi ai i nā kumukūʻai hana waikawa folic kūloko kiʻekiʻe, paʻakikī ke hoʻomaikaʻi i ka ʻike a me nā pilikia ʻē aʻe. Ua heluhelu ka mea kākau i kahi nui o nā palapala kūloko a me nā haole. Ma hope o nā hoʻokolohua a me nā haʻawina he nui, ua hoʻohui mākou i ka catalyst a kāohi i ka wikiwiki o ka chlorine, e hōʻemi ana i ka manawa hana i 1,1,3-3 trichloropacetone i loko o 24 mau hola, a me ka crystallization 1,1,3-3 trichloropacetone me ka maʻemaʻe ma mua o 99% a me ka hua o ka ʻoi aku ma mua o 45%.
