Intshayelelo
I-α-propyl-γ-butyrolactone (eyaziwa ngokuba yi-α-MBC) yinto eqhelekileyo ye-organic solvent. Inolwelo olungenambala nolungenavumba kwaye ineqondo eliphantsi lokuphuma komphunga kwiqondo lobushushu begumbi. Nazi iinkcukacha malunga ne-α-propyl-γ-butyrolactone:
Umgangatho:
- I-α-propyl-γ-butyrolactone ine-solubility egqwesileyo kwaye inokunyibilika izinto ezininzi eziphilayo ezifana ne-resin, iipende kunye neengubo.
- Le lactone ayinakutsha, kodwa inokuvelisa iigesi ezinetyhefu kumaqondo obushushu aphezulu.
Sebenzisa:
- I-α-Propyl-γ-butyrolactone isetyenziswa ngokubanzi kwiinkqubo zokuvelisa i-industrial for solvents, foams, paints, coatings, adhesives, kunye neemveliso zeplastiki.
Indlela:
- I-α-propyl-γ-butyrolactone idla ngokulungiswa nge-esterification ye-γ-butyrolactone. Kule nkqubo, i-γ-butyrolactone iphendula kunye ne-acetone kunye nokugqithisa kwe-hydrochloric acid okanye i-sulfuric acid yongezwa njenge-catalyst.
Ulwazi ngoKhuseleko:
- Xa uphethe i-α-propyl-γ-butyrolactone, gwema ukudibanisa ixesha elide kunye nesikhumba kunye ne-inhalation yeegesi.
- Amanyathelo afanelekileyo okhuseleko kunye nemimiselo kufuneka ilandelwe xa ugcina kwaye uphatha i-α-propyl-γ-butyrolactone.
