Hoʻolauna
ʻO ka Monochloroacetyl chloride (ʻike pū ʻia ʻo chloroyl chloride, acetyl chloride) he mea hoʻohuihui. Penei kona mau waiwai.
1. Nānā: wai kala ʻole a melemele paha;
2. ʻAla: ʻala ʻala kūikawā;
3. Ka nui: 1.40 g / mL;
Hoʻohana mau ʻia ka Monochloroacetyl chloride i ka synthesis organik a loaʻa iā ia nā hoʻohana penei:
1. Ma ke ʻano he acylation reagent: hiki ke hoʻohana ʻia no ka hopena esterification, ka mea e hana ai i ka waikawa me ka waiʻona e hana i ka ester;
2. Ma keʻano he acetylation reagent: hiki iā ia ke hoʻololi i ka atom hydrogen ikaika me kahi hui acetyl, e like me ka hoʻokomoʻana i nā hui hana acetyl i loko o nā meaʻala;
3. E like me ka chlorinated reagent: hiki iā ia ke hoʻokomo i nā ʻātoma chlorine ma ka inoa o nā ion chloride;
4. Hoʻohana ʻia e hoʻomākaukau i nā mea hoʻohui ʻē aʻe, e like me ketones, aldehydes, acids, etc.
Hoʻomākaukau ʻia ka Monochloroacetyl chloride ma nā ʻano penei:
1. Hoʻomākaukau ʻia e ka hopena o ka acetyl chloride a me ka trichloride, a ʻo nā huahana hopena he monochloroacetyl chloride a me trichloroacetic acid:
C2H4O + Cl2O3 → CCl3COCl + ClOCOOH；
2. Ka pane pololei o ka acetic acid me ka chlorine e hana ai i ka monochloroacetyl chloride:
C2H4O + Cl2 → CCl3COCl + HCl.
I ka wā e hoʻohana ai i ka monochloroacetyl chloride, pono e hoʻomaopopo ʻia kēia ʻike palekana:
1. He ʻala ʻala a me ka mahu, a pono e hana ʻia ma kahi e hoʻomaha maikaʻi ʻia;
2. ʻOiai ʻaʻole hiki ke puhi ʻia, e hana ʻino ia i ka wā e hālāwai ai me kahi kumu e hoʻā ai, e hana ana i nā kinoea ʻawaʻawa, a pono e mālama ʻia mai nā lapalapa ākea;
3. I ka hoʻohana ʻana a me ka mālama ʻana, pono e pale aku i ka hoʻopili ʻana me nā oxidants ikaika, alkalis, ka pauka hao a me nā mea ʻē aʻe e pale ai i nā hopena pōʻino;
4. He mea hoʻonāukiuki i kaʻili, nā maka a me ka'ōnaehana hanu, a pono e hanaʻia me nā mīkina lima, nā maka maka a me nā pale pale;
5. Inā loaʻa ka inhalation a i ʻole ka pili ʻana, e holoi koke i ka wahi i hoʻopilikia ʻia a e ʻimi i ke kōkua olakino inā loaʻa kekahi mau hōʻailona.
