Hoʻolauna

ʻO ka 3,4-Dichloropyridine he mea hoʻohuihui mea ola me ke ʻano kemika C5H3Cl2N. ʻO kēia ka wehewehe ʻana o kona ʻano, hoʻohana, hana a me ka ʻike palekana:

 

ʻAno:

-Nani: wai kala ʻole

-Ka helu hehee:-12 ℃

-Pila paila: 149-150 ℃

-Ka mānoanoa: 1.39 g/mL

-Solubility: Loaʻa iā ia ka solubility maikaʻi a hiki ke hoʻoheheʻe ʻia i loko o ka wai, ka waiʻona a me nā solvents ether.

 

E hoʻohana:

- Hiki ke hoʻohana ʻia ka 3,4-Dichloropyridine ma ke ʻano he reagent kemika a ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis organik.

-Hiki ke hoʻohana ʻia e synthesize i nā pūhui organik e like me nā pesticides, nā lāʻau lapaʻau a me nā mea hoʻonaninani.

-Ma ka ʻoihana uila, hoʻohana ʻia ia ma ke ʻano he mea maka no nā mea uhi a me nā mea optical.

 

Kaʻina hoʻomākaukau:

- Hiki ke loaʻa ka 3,4-Dichloropyridine ma ka hopena o ka pyridine me ka chlorine. Hiki ke hoʻololi i nā kūlana o ka hopena e like me nā mea hana a me nā koi o ka hale hana kūikawā.

 

ʻIke palekana:

- ʻO 3,4-Dichloropyridine kahi mea hoʻohuihui mea hoʻonāukiuki a ʻona paha. I ka wā e hoʻohana ai, e mālama pono e pale i ka inhalation o nā mahu a me ka pili ʻana me ka ʻili, nā maka a me nā membrane mucous.

-Ma ka hana, pono e lawe i nā mea palekana kūpono, e like me ke komo ʻana i nā mīkina lima, nā maka aniani a me nā lole pale.

-I ka mālama ʻana a me ka mālama ʻana, e mālama i ke ahi a me nā mea kūlohelohe e pale aku ai i nā ulia ahi a i ʻole nā ​​​​pahū.

-I ka wā e hoʻohana ai, e hahai i nā kaʻina hana palekana a mālama a hoʻolei aku i nā ʻōpala e like me nā kānāwai a me nā kānāwai o ka honua, aupuni a kūloko.

 

E ʻoluʻolu e hoʻomaopopo he hoʻolauna maʻamau kēia i ka 3,4-Dichloropyridine. ʻO ke ʻano kikoʻī, ka hoʻohana ʻana, ke ʻano hoʻomākaukau a me ka ʻike palekana e pono ke aʻo ʻia a loiloi hou ʻia e like me nā kūlana lab a me nā kūlana maoli.
