Gabatarwa
2,2-Bis (hydroxymethyl) 1,3-propanediol, wanda kuma aka sani da TMP ko trimethylalkyl triol, wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga kaddarorin sa, amfaninsa, hanyoyin masana'anta da bayanan aminci:
inganci:
- Bayyanar: 2,2-Bis (hydroxymethyl) 1,3-propanediol ruwa ne mara launi zuwa rawaya mai danko.
- Solubility: Yana narkewa cikin ruwa da nau'ikan kaushi na halitta kamar ethers, alcohols, da ketones.
- Kwanciyar hankali: Yana da ingantacciyar kwanciyar hankali a ƙarƙashin yanayin iskar shaka na al'ada, amma zai bazu a ƙarƙashin yanayin zafi da yanayin acidic.
Amfani:
- Abun tushe: 2,2-bis (hydroxymethyl) 1,3-propanediol shine tsaka-tsakin sinadarai da kayan albarkatun kasa, wanda za'a iya amfani dashi don haɗa sauran mahadi.
- Harshen wuta: Ana iya amfani da shi azaman mai ɗaukar wuta a cikin haɗin kayan aikin polymer na polyurea da kayan kwalliyar polymer.
- Shiri na ester mahadi: 2,2-Bis (hydroxymethyl) 1,3-propanediol za a iya amfani da su shirya ester mahadi, kamar polyol polyesters da polyester polymers.
Hanya:
Ana iya shirya shi ta hanyar motsa jiki na formaldehyde da methanol: na farko, formaldehyde da methanol suna amsawa tare da methanol a ƙarƙashin yanayin alkaline don samar da methanol hydroxyformaldehyde, sa'an nan kuma 2,2-bis (hydroxymethyl) 1,3-propanediol an kafa ta Halin daɗaɗɗa na bimolecules da methanol a ƙarƙashin yanayin acidic.
Bayanin Tsaro:
- 2,2-Bis (hydroxymethyl) 1,3-propanediol gabaɗaya lafiya ne a ƙarƙashin yanayin amfani na yau da kullun, amma yakamata a lura da waɗannan abubuwan:
- Maiyuwa ya zama gurɓata: Akwai 2,2-bis (hydroxymethyl) 1,3-propanediol na kasuwanci na iya ƙunsar ƙananan ƙazanta ko ƙazanta, don haka a kula don duba lakabin da siyan samfurori daga masu samar da abin dogara lokacin amfani da su.
- Haushin fata: Yana iya yin illa ga fata da idanu, sannan a dauki matakan kiyaye lafiya idan an taba su, kamar sanya safar hannu da tabarau na sinadarai, da nisantar saduwa ta kai tsaye.
- Yanayin ajiya: Ya kamata a adana fili a cikin duhu, bushe da wuri mai kyau, nesa da wuta, zafi mai zafi, da oxidants.
- Guba: 2,2-Bis (hydroxymethyl) 1,3-propanediol ba shi da guba, amma har yanzu ya kamata a kauce masa don sha ko sha.
