| Nā hōʻailona pōʻino | Xn – Poino |
| Nā Code Risk | R22 – Poino ke aleia R37/38 – Hoʻonanea i ka ʻōnaehana hanu a me ka ʻili. R41 – Ka pilikia o ka poino nui i na maka |
| Ka wehewehe palekana | S26 – Inā pili me nā maka, e holoi koke me ka wai nui a e ʻimi i ka ʻōlelo aʻo kino. S39 - Hoʻohana i ka pale maka / maka. |
Hoʻolauna
He pūhui olaola me ke kumu C6H5ClFN. He wai waihoʻoluʻu me kahi ʻala kūikawā. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
-Nani: wai kala ʻole
-ʻala: ʻAla kūikawā
-Ka mānoanoa: 1.36 g/mL
-Pila paila: 137-139 ℃
-Ka helu hehee:-4 ℃
-Solubility: Miscible me nā mea hoʻoheheʻe organik, aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
E hoʻohana:
Hoʻohana nui ʻia ia i ka synthesis organik a hiki ke hoʻohana ʻia ma ke ʻano he catalyst a i ʻole nā mea maka. Loaʻa iā ia nā noi koʻikoʻi i ka synthesis o nā pesticides, pharmaceuticals a me nā kemika, a hoʻohana mau ʻia i ka hana ʻana i nā pesticides, dyes, solvents, etc.
Ke Kaʻina Hoʻomākaukau: The preparation method of
ʻoi aku ka paʻakikī. ʻO ke ʻano hoʻomākaukau maʻamau ka loaʻa ʻana o 5-chloro -2-oxo -3-methyl pyridine ma o ka hopena chloro-propionaldehyde ma o pyridine ma ke ʻano he mea maka, a loaʻa ka huahana hope ma o ka hopena fluorination.
ʻIke palekana:
He pūhui organik ia, a pono e mālama pono ʻia kēia mau mea palekana i ka wā e hoʻohana ai:
-Ma muli o ka inhalation, pili a i ʻole ka ʻai ʻana. Pono e ʻalo ʻia ka pili pono ʻana me ka ʻili, nā maka a me nā membrane mucous.
-E hoʻohana i nā mea pale kūpono e like me nā mīkina lima, nā maka aniani a me nā lole pale ke hoʻohana ʻia.
-E hōʻalo i ka pilina me nā oxidants, nā ʻakika ikaika, nā kumu ikaika a me nā mea ʻē aʻe e pale aku i nā hopena palekana.
-Ke hiki mai ka leakage, pono e lawe ʻia nā hana kūpono e hoʻomaʻemaʻe i ka leakage a pale i ke komo ʻana i ka ʻōnaehana wai a me ke kaiapuni.
I ka hoʻohana ʻana i ka pūhui, e hana i nā ana palekana e like me ke kūlana maoli a nānā i ka pepa ʻikepili palekana o ka pūhui.
