DIMETHYLUREA wehewehe huahana
ʻO 1,1-Dimethylurea he mea hoʻohui kemika me ke ʻano mole mole C3H8N2O.ʻIke ʻia ʻo ia ʻo dimethylurea a i ʻole DMU.ʻO ia ka pauka crystalline keʻokeʻo, hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe organik.
Loaʻa ka 1,1-Dimethylurea i nā noi like ʻole i nā ʻoihana like ʻole.ʻO kekahi o kāna hoʻohana nui ʻana he reagent i ka synthesis organik.Hoʻohana maʻamau ia ma ke ʻano he kumu o ka dimethylamine, kahi poloka hale koʻikoʻi i ka hana ʻana i nā lāʻau lapaʻau, nā mea pena a me nā mea kemika ʻē aʻe.
I ka ʻoihana lāʻau lapaʻau, hoʻohana ʻia ʻo 1,1-dimethylurea ma ke ʻano he precursor no ka synthesis o nā lāʻau lapaʻau a me nā mea waena.
Hiki ke hoʻohana ʻia ma ke ʻano he mea pale no nā pūʻulu hana kemika i ka wā o nā hopena organik.Hoʻohana ʻia ia ma ke ʻano he catalyst i kekahi mau hopena.
Eia kekahi, hoʻohana ʻia ka 1,1-dimethylurea i ka synthesis o nā herbicides a me nā fungicides.Hana ia ma ke ʻano he stabilizer a hoʻonui i ka hana o kēia mau agrochemical.He mea koʻikoʻi loa ka mālama ʻana i ka 1,1-dimethylurea me ka mālama ʻana no ka mea ua manaʻo ʻia he mea pōʻino ke hoʻokomo ʻia a pili pū me ka ʻili a me nā maka.Pono e mālama pono i ka palekana i ka wā e hana ai me kēia pūhui, e like me ke komo ʻana i nā mea pale a me ka hōʻoia ʻana i ka ea maikaʻi.
I ka hōʻuluʻulu ʻana, ʻo 1,1-dimethylurea kahi hui multifunctional hiki ke hoʻohana ʻia i ka synthesis organik, nā lāʻau lapaʻau, a me nā agrochemical.Hoʻohana ʻia kona waiwai ma ke ʻano he reagent, pale, a me ka catalyst i nā ʻano hana kemika.
