Hoʻolauna
ʻO 2,2-Bis(hydroxymethyl) 1,3-propanediol, i ʻike ʻia ʻo TMP a i ʻole trimethylalkyl triol, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana.
ʻAno maikaʻi:
- Ke ʻano: 2,2-Bis(hydroxymethyl)1,3-propanediol he wai kala ʻole i ka melemele viscous wai.
- Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai a me nā ʻano mea hoʻoheheʻe kūlohelohe e like me nā ethers, nā ʻona, a me nā ketones.
- Paʻa: Paʻa ia ma lalo o nā kūlana oxidation maʻamau, akā e hoʻoheheʻe ʻia ma lalo o ke kiʻekiʻe kiʻekiʻe a me nā kūlana acidic.
E hoʻohana:
- Ka waiwai kumu: 2,2-bis(hydroxymethyl) 1,3-propanediol he mea hoʻohui kemika a me nā mea maka, hiki ke hoʻohana ʻia e synthesize i nā mea hoʻohui ʻē aʻe.
- Hoʻopaʻa ahi: Hiki ke hoʻohana ʻia ma ke ʻano he ahi ahi i ka synthesis o nā mea polyurea polymer a me nā uhi polymer.
- Ka hoʻomākaukauʻana i nā pūhui ester: 2,2-Bis (hydroxymethyl) 1,3-propanediol hiki ke hoʻohanaʻia no ka hoʻomākaukauʻana i nā pūhui ester, e like me ka polyol polyesters a me ka polyester polymers.
Hanana:
- Hiki ke hoʻomākaukau ʻia e ka hopena condensation o ka formaldehyde a me ka methanol: ʻo ka mua, ua hana ʻia ka formaldehyde a me ka methanol me ka methanol ma lalo o nā kūlana alkaline e hana i ka methanol hydroxyformaldehyde, a laila hoʻokumu ʻia ka 2,2-bis(hydroxymethyl)1,3-propanediol e ka ka hopena condensation o nā bimolecules a me ka methanol ma lalo o nā kūlana ʻakika.
ʻIke palekana:
- 2,2-Bis(hydroxymethyl)1,3-propanediol ka palekana ma lalo o nā kūlana maʻamau o ka hoʻohana ʻana, akā pono e hoʻomaopopo ʻia kēia mau mea:
- Hiki ke hoʻohaumia: Loaʻa i ka 2,2-bis(hydroxymethyl)1,3-propanediol ma ke kūʻai kūʻai ʻana i nā wahi liʻiliʻi o nā haumia a i ʻole nā mea haumia, no laila e makaʻala e nānā i ka lepili a kūʻai aku i nā huahana mai nā mea kūʻai pono i ka wā e hoʻohana ai.
- Hoʻopilikia ka ʻili: He hopena hoʻonāukiuki paha ia ma ka ʻili a me nā maka, a pono e mālama ʻia nā mea palekana e pono ai ke hoʻopā ʻia, e like me ke komo ʻana i nā mīkina lima kemika a me nā maka aniani, a me ka pale ʻana i ka pilina pololei.
- Nā kūlana mālama: Pono e mālama ʻia ka pūhui ma kahi ʻeleʻele, maloʻo a me ka makani maikaʻi, ma kahi mamao mai ke ahi, nā wela kiʻekiʻe, a me nā mea ʻona.
- He mea ʻawaʻawa: 2,2-Bis(hydroxymethyl)1,3-propanediol ʻaʻole liʻiliʻi, akā pono e pale ʻia no ka ingestion a i ʻole inhalation.
