DIMETHYLUREA Chigadzirwa Tsananguro
1,1-Dimethylurea ikemikari yemakemikari ine molecular formula C3H8N2O.Iyo inozivikanwawo se dimethylurea kana DMU.Iyo chena crystalline poda, inonyungudika nyore mumvura uye organic solvents.
1,1-Dimethylurea ine maitiro akasiyana-siyana mumaindasitiri akasiyana.Imwe yemashandisirwo ayo makuru ndeye reagent mune organic synthesis.Inowanzoshandiswa sechitubu che dimethylamine, chivakwa chakakosha chekuvaka mukugadzirwa kwemishonga, dhayi uye mamwe makemikari.
Muindasitiri yemishonga, 1,1-dimethylurea inoshandiswa sefanotungamira yekubatanidza zvinodhaka nepakati pezvinodhaka.
Inogona kushandiswa sechidziviriro chekudzivirira chemakemikari anoshanda emapoka panguva yehupenyu hwekuita.Inoshandiswawo secatalyst mune mamwe maitiro.
Mukuwedzera, 1,1-dimethylurea inoshandiswawo mukugadzirwa kwemishonga yesora uye fungicides.Inoshanda seyakagadzikana uye inowedzera kushanda kweagrochemicals aya.Zvinonyanya kukosha kubata 1,1-dimethylurea nekuchenjerera nokuti inonzi inokuvadza kana ikabatwa kana kusangana neganda kana maziso.Matanho akakodzera ekuchengetedza anofanirwa kutorwa paunenge uchishanda nekomboni iyi, sekupfeka midziyo yekudzivirira uye kuona mhepo yakanaka.
Muchidimbu, 1,1-dimethylurea isanganiswa yakawanda inogona kushandiswa muorganic synthesis, pharmaceuticals, uye agrochemicals.Zvimiro zvayo zvinoita kuti zvive zvakakosha se reagent, kudzivirira, uye catalyst mumhando dzakasiyana dzemakemikari maitiro.
