Propargyl o le a polymerize ma pa
O le fa'agasologa muamua e fa'avae i luga o le ava malosi propargyl e pei o le solvent, KOH e pei o le fa'avae, fa'avevela tali e maua ai le fa'amoemoe.Reaction e aunoa ma solvent dilution tulaga o le a faaitiitia eleelea, o le tali e mama.
Mafaufau i le mafai ona fa'apipi'iina fa'apea ma le pala o alkynes fa'amau, o le Amgen's Hazard Evaluation Lab (HEL) na laa i totonu e fa'atino su'esu'ega mo le saogalemu ma fesoasoani i le fa'avasegaina o le fa'agasologa a'o le'i fa'ateleina i le 2 lita o le tali.
O le suʻega DSC o loʻo faʻaalia ai o le tali e amata ona pala i le 100 °C ma faʻamalolo 3667 J / g le malosi, aʻo faʻatasi le propargyl alcohol ma KOH, e ui ina pa'ū le malosi i le 2433 J / g, ae o le vevela o le decomposition e pa'ū foi i le 85 °C, ma ole vevela ole faagasologa e latalata tele ile 60 °C, e sili atu le lamatiaga o le saogalemu.
