Ọpụrụiche na mmepụta nke mmanya propargyl, 1,4 butynediol na 3-chloropropyne.
Propargyl ga-agbawa ma gbawaa
Usoro izizi dabere na mmanya propargyl dị ka ihe mgbaze, KOH dị ka ntọala, mmeghachi omume kpo oku iji nweta ebumnuche.Mmeghachi omume na-enweghị ọnọdụ dilution ihe mgbaze ga-abụ obere adịghị ọcha, mmeghachi omume dị ọcha.
N'ịtụle ike polymerization catalytic na mwepu mgbawa nke ọdụ ụgbọ elu alkynes, Amgen's Hazard Evaluation Lab (HEL) abanyela iji mee nyocha nchekwa ma nyere aka n'ịkwalite usoro tupu iwelie ihe ruru lita 2 nke mmeghachi omume.
Nnwale DSC na-egosi na mmeghachi omume ahụ na-amalite ire ere na 100 Celsius ma hapụ 3667 J / g ume, ebe mmanya propargyl na KOH ọnụ, ọ bụ ezie na ike na-adaba na 2433 J / g, mana okpomọkụ decomposition na-adaba na 85 ° C, na Usoro okpomọkụ dị nso na 60 Celsius C, ihe ize ndụ nchekwa dị ukwuu.
Ejiri Yoshida Correction gbakọọ data DSC, nsonaazụ ya gosiri na ma mmanya propargyl na ngwọta potassium hydroxide na-enwe mmetụta mmetụta na mgbawa.
Ntughari nke kinetic site na iji AKTS weputara TD24 nke 73.5 Celsius C maka mmanya propargyl dị ọcha na 45.9 Celsius C maka ngwọta 3 M KOH.Ya mere, usoro ahụ adịghị mma maka ibuwanye elu.
Ọzọkwa nwalee azịza mmeghachi omume na ARC, a obere okpomọkụ ntọhapụ na 46 Celsius C, adiabatic okpomọkụ ịrị elu nke 6 Celsius C, kwesịrị ịbụ ebumnuche mmeghachi omume ntọhapụ okpomọkụ.Na 76 Celsius C, enwere ọkụ siri ike na ntọhapụ gas, nke mere ka tank ule ahụ gbawa ozugbo.A na-egosikwa na mmeghachi omume adịghị mma maka mmụba.
HEL na ndị otu ahụ tụlere mgbanwe ntọala, mana nyocha DSC gosiri na ọbụna ọnụnọ nke isi wedatara okpomọkụ ire ere nke mmanya propargyl.
Nnwale nyocha nke iji alkali gosipụtara na mmeghachi omume KOH dị mma.Nnyocha ọzọ nke ihe mgbaze gosiri na dioxane bụ mmeghachi omume ka mma.Nnwale ARC gosiri na mgbe mmeghachi omume exothermic nke mmeghachi omume ebumnuche, ọnọdụ okpomọkụ gara n'ihu na-arị elu ruo 200 Celsius ma ka ahụghị nbibi siri ike.Enwere ike ibuli ọnọdụ a n'enweghị nsogbu.
