Folasaga

2,2-Bis (hydroxymethyl) 1,3-propanediol, e taʻua foi o le TMP poʻo le trimethylalkyl triol, o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i ona meatotino, fa'aoga, auala gaosi ma fa'amatalaga saogalemu:

Tulaga lelei:

- Fa'aaliga: 2,2-Bis(hydroxymethyl) 1,3-propanediol o se vai e leai se lanu i le samasama viscous.

- Solubility: E solu i le vai ma le tele o solu faʻaletino e pei ole ethers, ava malosi, ma ketones.

- Fa'amautu: E fai si mautu i lalo o tulaga fa'ama'i fa'amasani, ae o le a pala i lalo o le maualuga o le vevela ma tulaga oona.

Fa'aaogā:

- Mea fa'avae: 2,2-bis(hydroxymethyl) 1,3-propanediol o se vaila'au vavalo ma mea fa'avae, lea e mafai ona fa'aoga e fa'apipi'i ai isi mea fa'aola.

- Faʻasaʻo mumu: E mafai ona faʻaaogaina e avea o se afi mumu i le tuʻufaʻatasia o mea polyurea polymer ma polymer coatings.

- Sauniuniga o mea faʻapipiʻi ester: 2,2-Bis(hydroxymethyl) 1,3-propanediol e mafai ona faʻaogaina e saunia ai mea faʻapipiʻi ester, e pei o polyol polyesters ma polyester polymers.

Metotia:

- E mafai ona saunia e ala i le condensation tali o formaldehyde ma methanol: muamua, formaldehyde ma methanol e tali atu i le methanol i lalo o tulaga alkaline e fausia ai le methanol hydroxyformaldehyde, ona faia ai lea o le 2,2-bis(hydroxymethyl)1,3-propanediol e le fa'afefeteina o le bimolecules ma le methanol i lalo ole tulaga oona.

Fa'amatalaga Saogalemu:

- 2,2-Bis(hydroxymethyl)1,3-propanediol e masani ona saogalemu i lalo o tulaga masani o le faʻaaogaina, ae tatau ona matauina mea nei:

- Atonu e afaina: 2,2-bis(hydroxymethyl)1,3-propanediol o loʻo maua faʻapisinisi e mafai ona i ai ni nai mea leaga poʻo ni mea leaga, o lea ia faʻaeteete e siaki le igoa ma faʻatau oloa mai kamupani faʻalagolago pe a faʻaaogaina.

- Fa'aleagaina le pa'u: E ono i ai se aafiaga ita i le pa'u ma mata, ma e tatau ona faia ni puipuiga talafeagai pe a pa'i atu, e pei o le ofuina o totini lima ma mata tioata, ma aloese mai fesootaiga tuusao.

- Tulaga e teu ai: E tatau ona teu le mea faʻapipiʻi i se nofoaga pogisa, mago ma faʻafefe lelei, mamao ese mai afi, vevela maualuga, ma mea faʻamaʻi.

- Oona: 2,2-Bis(hydroxymethyl)1,3-propanediol e itiiti le oona, ae tatau lava ona aloese mai le ingestion poʻo le inhalation.
