Glycolaldehyde dimethyl acetal（CAS# 30934-97-5)

Folasaga

Hydroxyacetaldehyde dimethylacetal (2,2-dimethyl-3-hydroxybutyraldehyde) o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i lona natura, fa'aoga, auala sauniuni ma fa'amatalaga saogalemu:

Tulaga lelei:

1. Hydroxyacetaldehyde dimethylacetal o se vai suau'u e le lanu samasama ma se manogi manogi fa'apitoa.

2. E faigofie ona faʻafefeteina, e mafai ona faʻafefiloi i le ethanol ma le chloroform, ma e mafai ona solu i le vai.

3. O le fa'aupuga e a'afia i le aldehyde compound, lea e fa'aitiitia ma e mafai ona tali atu i nisi fa'ama'i.

Fa'aaogā:

1. O loʻo faʻaaogaina e avea o se mea taua tele i nisi o gaioiga faʻasolosolo faʻasolosolo, e pei o le tuʻufaʻatasia o vitamini B6 ma benzidine ma isi mea faʻapipiʻi.

2. O lo'o fa'aaogaina e fai ma mea muamua mo nisi o lanu felanulanua'i, po'o se mea e fa'aitiitia ai le fa'atupuina o meaola.

Metotia:

E tele auala e saunia ai le hydroxyacetaldehyde dimethylacetal, ma o le auala masani e maua mai i le resorcinol ma le acetone reaction. O laasaga faʻapitoa e faʻapea: resorcinone e muamua faʻafefe i le agarose poʻo le vaiinu ava malosi e fausia ai le glycidyl, ma faʻamafanafanaina i le acetone i lalo o tulaga faʻamaʻi e maua ai le hydroxyacetaldehyde dimethylacetal.

Fa'amatalaga Saogalemu:

1. Pe a fa'aogaina pe teu le vaila'au, aloese mai le manavaina o ona ausa ma fa'afeso'ota'i ma le pa'u ma mata.

2. A fa'aoga, e tatau ona fa'alogo lelei i le fa'aogaina o mea faigaluega e puipuia ai le tagata lava ia, e pei o le ofuina o totigilima puipui, mata tioata ma matapulepule puipui.

3. E tatau fo'i ona tausisia fa'atonuga o le fa'agaioiina o le saogalemu ma fa'atonuga o le pulega o vaila'au.
