Inzobere mu gukora inzoga za propargyl, 1,4 butynediol na 3-chloropropyne

Propargyl izahindura polymerize kandi iturike

Ibisobanuro bigufi:

Inzira yambere ishingiye kuri alcool ya propargyl nkibishishwa, KOH nkibishingwe, gushyushya reaction kugirango ubone intego.Igisubizo kidafite imiterere yo kugabanuka kizaba umwanda muke, reaction irasukuye.

Urebye ibishobora guterwa na polymerisime no guturika guturika kwa alkynes, Laboratwari ya Hazard Evaluation ya Amgen (HEL) yinjiye kugira ngo isuzume umutekano kandi ifashe mu buryo bunoze mbere yo gupima litiro 2 za reaction.

Ikizamini cya DSC cyerekana ko reaction itangira kubora kuri 100 ° C ikarekura ingufu za 3667 J / g, mugihe inzoga ya propargyl na KOH hamwe, nubwo ingufu zigabanuka zikagera kuri 2433 J / g, ariko ubushyuhe bwangirika nabwo bukamanuka kuri 85 ° C, kandi ubushyuhe bwibikorwa buri hafi ya 60 ° C, ibyago byumutekano ni byinshi.

Propargyl izakora polymerize kandi iturike2

Ikosorwa rya Yoshida ryakoreshejwe mu kubara amakuru ya DSC, kandi ibisubizo byerekana ko byombi inzoga ya propargyl hamwe na potasiyumu hydroxide ibisubizo bibangamira ibintu biturika kandi biturika.

Propargyl izakora polymerize kandi iturike3

Gusubira inyuma kwa Kinetic ukoresheje AKTS byatanze TD24 ya 73.5 ° C kuri alcool ya propargyl yuzuye na 45.9 ° C kubisubizo byayo 3 M KOH.Kubwibyo, sisitemu ntabwo ikwiriye gukuzwa.

Ongera ugerageze igisubizo cyibisubizo hamwe na ARC, ubushyuhe buke kuri 46 ° C, ubushyuhe bwa adiabatic bwa 6 ° C, bigomba kuba intego yo kurekura ubushyuhe.Kuri 76 ° C, habaye ubushyuhe bukabije na gaze, ibyo bikaba byaratumye ikigega cyipimisha giturika.Byerekanwe kandi ko reaction idakwiriye kwongera.

Propargyl izakora polymerize kandi iturike4

HEL hamwe nitsinda batekereje guhindura ishingiro, ariko ibizamini bya DSC byerekanaga ko no kuba shingiro ryaragabanije ubushyuhe bwangirika bwinzoga ya propargyl.

Propargyl izahindura polymerize kandi iturike5

Ubushakashatsi bwerekanwe ukoresheje alkali bwerekanye ko reaction ya KOH yari nziza.Kongera gusuzuma ibishishwa byerekanaga ko dioxane yari reaction nziza.Ibizamini bya ARC byerekanye ko nyuma yimyitwarire ya exothermic reaction yintego, ubushyuhe bwakomeje kuzamuka kugera kuri 200 ° C kandi nubu nta kubora gukabije kwabonetse.Iyi miterere irashobora kwaguka neza.
