Hoʻolauna
ʻO 4-Methoxy-2,5-dimethyl-3 (2H) -furanone) he mea hoʻohui kino, i hoʻopau pinepine ʻia ʻo MDMF. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:
ʻAno maikaʻi:
- Ke ʻano: ʻAʻole waihoʻoluʻu i ka wai melemele ʻeleʻele
- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka hapa nui o nā mea hoʻoheheʻe organik e like me nā waiʻona, nā ethers a me nā ketones
E hoʻohana:
- Hoʻohana pinepine ʻia ʻo MDMF ma ke ʻano he intermediate i ka synthesis organik no ka synthesis o nā pūhui organik like ʻole.
- Hiki ke hoʻohana ʻia e like me ka solvent a me ka reactant i loko o nā laboratories kemika.
Hanana:
Hana ʻia ke ʻano hoʻomākaukau o MDMF e nā ʻanuʻu aʻe:
1. Hoʻopili ʻia ka P-toluene me ka hydroxyacetone no ka isomerization waiʻona ketone ma lalo o nā kūlana acidic.
2. Hoʻopili ʻia ka huahana me ka methanol e hana i nā pūhui waiʻona ketone.
3. Hoʻomaʻemaʻe ʻia nā pūhui waiʻona ketone e ka hopena dehydration a i ʻole ka mālama ʻana i kahi mea hoʻoheheʻe wai no ka hoʻoulu ʻana i ka huahana MDMF.
ʻIke palekana:
- He hopena hoʻonāukiuki ka MDMF ma ka ʻili a pono e holoi ʻia me ka wai nui ma hope koke o ka hoʻopili ʻana.
- Hiki ke hoʻoulu ʻia ka maka a me ka pōʻino o ka maka inā komo ia i loko o nā maka, no laila e holoi me ka wai nui ma hope koke o ka launa ʻana a nīnau i ke kauka.
- Hōʻalo i ka hanu ʻana i nā mahu o MDMF e pale aku i ka ʻeha hanu.
- Pono e ʻalo ʻia nā wela kiʻekiʻe, nā kumu hoʻāla, a me nā mea hoʻoneʻe ikaika i ka wā e mālama ai.
