Hana kūikawā i ka hana ʻana i ka waiʻona propargyl, 1,4 butynediol a me 3-chloropropyne

3-chloropropyne waihoʻoluʻu ʻona ʻona wai ʻona

ʻO ka wehewehe pōkole:

ʻO ka 3-chloropropyne kahi mea hoʻohuihui me ke ʻano hana ch ≡ cch2cl.ʻO ka hiʻohiʻona he wai lapalapa ʻole.ʻO ka helu heheʻe -78 ℃, kahi e hoʻolapalapa ai 57 ℃ (65 ℃), pili pili 1.0297, kuhikuhipuʻu refractive 1.4320.ʻO ke kiko uila 32.2-35 ℃, aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai a me ka glycerol, hiki ke hui pū me benzene, carbon tetrachloride, ethanol, ethylene glycol, ether a me ethyl acetate.Loaʻa ia ma ka hana ʻana i ka waiʻona propargyl me ka phosphorus trichloride.Hoʻohana ʻia ma ke ʻano he waena i ka synthesis organik.

Kaʻina hoʻomākaukau: Loaʻa ia ma ka hana ʻana i ka waiʻona propargyl me ka phosphorus trichloride.ʻO ka mea mua, hoʻohui ʻia ka aila ahi a me ka phosphorus trichloride i loko o ka pahu hoʻoheheʻe maloʻo, a hoʻohui ʻia ka hui ʻana o ka waiʻona propargyl a me ka pyridine ma lalo o 20 ℃.Ma hope o ka hoʻohui ʻana, ua wela ia i ka reflux.Ma hope o ka hopena no 4 mau hola, hoʻohui ʻia i loko o ka wai hau e hoʻokaʻawale i ka papa wai.Hoʻohui ʻia ka ʻaila ʻaila me ka puka aniani wai sodium carbonate i ph=5-6 e hoʻokaʻawale i ka papa wai, a laila holoi ʻia, maloʻo a hoʻoheheʻe ʻia ma lalo o ke kaomi maʻamau e hōʻiliʻili i nā hakina 52-60 ℃ no ka loaʻa ʻana o ka huahana i hoʻopau ʻia.

Waihona:hale kūʻai i loko o kahi hale kūʻai anuanu a me ka ea.E mālama i ke ahi a me ke kumu wela.E pale i ka lā pololei a hoʻopaʻa i nā pahu.Pono e hoʻohana ʻia nā kukui pahū a me nā mea hoʻoheheʻe.ʻAʻole ʻae ʻia ka hoʻohana ʻana i nā mea hana mechanical a me nā mea hana maʻalahi e hana i nā huna huna.E hoʻolako ʻia ka wahi mālama me nā lako lapaʻau ulia pōpilikia a me nā mea lawe kūpono.

Ke kumu:Hoʻohana ʻia ia i ka hana ʻana i ka lāʻau youjiangning, fumigant lepo, a me nā mea ʻē aʻe.ʻO kāna paʻakai trisodium he mea hoʻomaha wela maikaʻi loa no PVC, a ʻo kāna esters kekahi mau mea hoʻohui nui no nā polymers.

ʻO ke kaʻina hana chlorpropargyne i hāpai ʻia e kā mākou hui ʻo ia ka hana ʻana o ka chlorpropargyne e ka propargyl alcohol a me ka thionyl chloride ma lalo o ka hana a DMF.He mau ala maʻalahi kēia ʻano, ʻo 100% ka hoʻololi hoʻololi ʻana o ka waiʻona propargyl, a mālama ka DMF i ke kahe ʻana me ka ʻole o ka poho, me ka ʻole o ka hoʻonui ʻana i waho, me ke kaʻina pōkole a me nā lako liʻiliʻi.I ka manawa like, ʻike ia i ka hana mau.ʻO ia ka hana kemika mua no ka hana mau ʻana o ka chlorpropargyne ma Kina
