Hoʻolauna
Diethyl chloromalonate (ʻike pū ʻia ʻo DPC). ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o diethyl chloromalonate:
1. ʻAno:
- Ke ʻano: Diethyl chloromalonate he wai kala ʻole.
- Hiki ke hoʻoheheʻe ʻia: Hiki ke hoʻoheheʻe ʻia i loko o ka hapa nui o nā mea hoʻoheheʻe kūlohelohe, e like me nā waiʻona, eter, a me nā hydrocarbons ʻala, akā hiki ke hoʻoheheʻe ʻia i ka wai.
- Paʻa: Paʻa ia i ka māmā a me ka wela, akā hiki ke hana i ke kinoea hydrogen chloride ʻawaʻawa ma nā wela kiʻekiʻe a i ʻole ke ahi hāmama.
2. Hoʻohana:
- Ma ke ʻano he mea hoʻoheheʻe: Hiki ke hoʻohana ʻia ʻo Diethyl chloromalonate ma ke ʻano he mea hoʻoheheʻe, ʻoi aku ka nui o ka synthesis organik e hoʻoheheʻe a hana i nā pūhui organik.
- Hoʻohui kemika: He mea hoʻohana maʻamau ia no ka synthesis o nā esters, amides, a me nā mea hoʻohui ʻē aʻe.
3. Keʻano:
- Hiki ke loaʻa ka Diethyl chloromalonate ma ka hopena o diethyl malonate me ka hydrogen chloride. ʻO nā kūlana hoʻololi maʻamau ma ka lumi wela, hoʻokomo ʻia ke kinoea hydrogen chloride i loko o ka malonate diethyl, a hoʻohui ʻia kahi catalyst e hāpai i ka hopena.
- Ka hoohalike ana: CH3CH2COOCH2CH3 + HCl → ClCH2COOCH2CH3 + H2O
4. ʻIke palekana:
- He ʻala ʻono ka Diethyl chloromalonate a hiki ke hōʻeha i ka ʻili, nā maka, a me ka ʻōpū hanu.
- He wai wela ia e pono e mālama ʻia ma kahi ʻoluʻolu a me ka ea maikaʻi a ma kahi mamao aku i nā kumu ahi a me nā lapalapa ākea.
- Pono e ʻaʻahu ʻia nā mea pale ponoʻī e like me nā mīkina lima, nā maka aniani, a me nā lole pale i ka wā e lawelawe ai.
