Propargyl ichaita polymerize uye kuputika
Iyo yekutanga maitiro yakavakirwa papropargyl doro se solvent, KOH se base, yekudziya kuita kuti uwane chinangwa.Reaction pasina solvent dilution mamiriro achave mashoma kusvibiswa, maitiro akachena.
Tichifunga nezve inogona kuita catalytic polymerization uye kuputika kuparara kweiyo terminal alkynes, Amgen's Hazard Evaluation Lab (HEL) yakapinda kuti iite ongororo yekuchengetedza uye kubatsira mukugadzirisa mashandiro isati yawedzera kusvika 2 malita emhinduro.
DSC bvunzo inoratidza kuti maitiro anotanga kuora pa100 ° C uye kuburitsa 3667 J / g simba, nepo propargyl doro neKOH pamwe chete, kunyangwe simba richidonha kusvika 2433 J / g, asi tembiricha yekuora inodonhawo kusvika 85 ° C, uye tembiricha yemaitiro iri padyo zvakanyanya kusvika 60 °C, njodzi yekuchengetedza yakakura.
