Intshayelelo

I-organic compound kunye ne-molecular formula ye-C6H6BrClN kunye ne-molecular weight of 191.48g / mol. Oku kulandelayo yintshayelelo kubume bayo, ukusetyenziswa, ukuqulunqwa kunye nolwazi lokhuseleko:

Indalo:

-Inkangeleko: Ayinabala ukuya kolutyheli okuqinileyo.

-Indawo yokunyibilika: malunga ne-20-22°C.

-Indawo yokubila: malunga ne-214-218 °C.

-I-Solubility: I-Soluble kwi-ethanol kunye ne-chloroform, ayinyibiliki emanzini.

Sebenzisa:

-yinto ebalulekileyo ye-organic synthesis intermediate, esetyenziswa ngokubanzi kwi-synthesis yezinye iikhompawundi.

-inokusetyenziswa ukulungiselela iintlobo zeziyobisi kunye ne-pesticide intermediates, ezifana ne-naphtha insecticides, iziyobisi ze-ketol.

Indlela:

Okwangoku, indlela yokulungiselela esetyenziswa ngokuqhelekileyo ifunyenwe ngokuphendula i-2-picoline chloride kunye ne-lithium bromide.

Ulwazi ngoKhuseleko:

-ikhompawundi ecaphukisayo enokubangela ukucaphuka kunye nokuvuvukala ngokudibana nolusu kunye namehlo. Amanyathelo afanelekileyo okukhusela, afana neeglavu zelebhu, iiglasi kunye neengubo zelebhu, kufuneka zinxitywe ngexesha lokuphatha kunye nokugcinwa.

-Inokuba yityhefu kwizinto eziphilayo zasemanzini, kwaye kufuneka kuthathwe ukunakekelwa ukuze kuphephe ukungena kumzimba wamanzi.

-Le khompawundi kufuneka igcinwe kude nomlilo kunye nobushushu obuphezulu ukuthintela ukutsha kwayo okuzenzekelayo kunye nokudubula. Gcina kwindawo epholileyo, eyomileyo kwaye engenamoya.
