Hordhac
2,2-Bis (hydroxymethyl) 1,3-propanediol, oo sidoo kale loo yaqaan TMP ama trimethylalkyl triol, waa unug dabiici ah. Kuwa soo socdaa waa horudhac ku saabsan hantideeda, adeegsigeeda, hababka wax-soo-saarka iyo macluumaadka badbaadada:
Tayada:
- Muuqashada: 2,2-Bis (hydroxymethyl) 1,3-propanediol waa dareere aan midab lahayn ama huruud ah.
- Solubility: Waxay ku milmi kartaa biyaha iyo noocyo kala duwan oo dareerayaasha organic sida ethers, alcohols, iyo ketones.
- Xasilooni: Way xasiloon tahay xaaladaha oksaydhaynta caadiga ah, laakiin waxay ku dumin doontaa heerkulka sare iyo xaaladaha acidic.
Isticmaal:
Walaxda saldhigga ah: 2,2-bis (hydroxymethyl) 1,3-propanediol waa kiimiko dhexdhexaad ah iyo walxo cayriin oo aasaasi ah, kaas oo loo isticmaali karo in lagu soo saaro xeryahooda kale ee dabiiciga ah.
- Dab-demiska: Waxaa loo isticmaali karaa sidii ololka dab-demiska ee isku-dhafka maaddooyinka polymer-ka ee polyurea iyo daahan polymer.
- Diyaarinta xeryahooda ester-ka: 2,2-Bis (hydroxymethyl) 1,3-propanediol ayaa loo isticmaali karaa in lagu diyaariyo xeryahooda ester-ka, sida polyester-ka polyol iyo polyester-ka.
Habka:
Waxaa lagu diyaarin karaa falcelinta uumiga ee formaldehyde iyo methanol: marka hore, formaldehyde iyo methanol waxaa lagu falceliyaa methanol hoostooda xaaladaha alkaline si ay u sameeyaan methanol hydroxyformaldehyde, ka dibna 2,2-bis (hydroxymethyl) 1,3-propanediol waxaa sameeyay falcelinta uumiga ee bimolecules iyo methanol ee xaaladaha acidic.
Macluumaadka Badbaadada:
- 2,2-Bis (hydroxymethyl) 1,3-propanediol guud ahaan waa ku badbaado xaaladaha caadiga ah ee isticmaalka, laakiin kuwan soo socda waa in la ogaadaa:
- Waxa laga yaabaa inay wasakhaysan tahay: Ganacsiga la heli karo 2,2-bis(hydroxymethyl)1,3-propanediol waxa ku jiri kara xaddi yar oo wasakh ah ama wasakh ah, markaa ka taxdar inaad hubiso calaamada oo aad ka iibsato alaab-qeybiyeyaal lagu kalsoonaan karo marka aad isticmaalayso.
- Xanaaq maqaarka: Waxa laga yaabaa in ay saameyn xun ku yeelato maqaarka iyo indhaha.
- Xaaladaha kaydinta: Xarunta waa in lagu kaydiyaa meel mugdi ah, qalalan oo hawo fiican leh, kana fog dabka, heerkulka sare, iyo oksidayaasha.
- Sunta: 2,2-Bis (hydroxymethyl) 1,3-propanediol way ka yar tahay sunta, laakiin wali waa in laga fogaadaa nuugista ama neefsashada.
