● wehewehe wehewehe: 1, 3-dimuthtylurea he urea drivative a hoʻohanaʻia e like me kahi waena waena o ka synthes organic. He mea nuiʻole nā kukui crystallineʻole me ka leʻaleʻa liʻiliʻi. Hoʻohanaʻia ia no ka synthesis o ka caffeine, nā mea kanu lāʻau, nā mea kanu lāʻau, nā mea kanu a me nā mea kanu. I ka hoʻohanaʻana i kaʻoihana hoʻoiliʻana 1,3-Dimometylurea e like me ke kikowaena no ka hanaʻana i ka hana no nā mea kūʻai aku no nā leka uila. Ma ka hua'ōlelo Swiss huahana he 38 mau huahana e loaʻa ana i ka 1,3-dimethylurea, i waena o lākou mau huahana 17 mau huahana i hoʻohanaʻia no ka hoʻohanaʻana. E like me nāʻano huahana e like me nāʻeha a me nā mea hoʻomaʻemaʻe hoʻomaʻemaʻe. ʻO nā manaʻo o 1,3-dimethylurea i nā huahana kūʻai aku a hiki i ka 10% (Swiss Fistrict Crent, 2003). E hoʻohana i nā cosmetics i manaʻoʻia, akāʻaʻoheʻike iʻikeʻia e like me kona hoʻohana maoliʻana i loko o kēia mau noi. He mea paʻaʻole ka crystalline crystalline me ka momona kiʻekiʻe i ka wai. Ua hoʻohana pinepineʻiaʻo 1,3-diziylurea ma kahi o ka stevent a me ka catalyst i ka synthes organice. Hiki ke hoʻohanaʻia i loko o ka synthesis o nā mea hoʻohui likeʻole e like me nā dyes, nā dysties fluorescent, a me nā plasticscent. Ma kaʻoihana lāʻau lapaʻau, 1,3-Dimometylurea e hoʻohana pūʻia e hoʻopili ai i kekahi mau intermeditical lāʻau lapaʻau. Kikeʻikaʻiʻia, hoʻohanaʻia ma nāʻoihana e like me ke kapa a me nā hoʻoponopono. He mea nui ia e hoʻomaopopo i kēlā me 1,3-dimutylurea e hoʻonāukiuki i kaʻili a me nā maka, no laila e mālama ponoʻia nā hana palekana.
● USES: N, N'-Dimometylurea hiki ke hoʻohanaʻia: e like me kahi mea e hoʻomaka ai e hoʻopili i nā mea e hoʻopili ai i n I ka hui pūʻana me β-cycloextrins derivatives, e hana i nāʻano haʻahaʻa haʻahaʻa (lmms)
