Nyanzvi mukugadzira propargyl doro, 1,4 butynediol uye 3-chloropropyne.
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.
Yoshida Correction yakashandiswa kuverenga DSC dhata, uye mhedzisiro inoratidza kuti zvese propargyl doro uye potassium hydroxide mhinduro inokanganisa uye inoputika.
Kinetic regression uchishandisa AKTS yakapa TD24 ye73.5 °C yepureggil doro rakachena uye 45.9 °C kune yayo 3 M KOH mhinduro.Naizvozvo, sisitimu haina kukodzera kukwidziridzwa.
Kuenderera mberi kuyedza mhinduro yemhinduro neARC, diki kupisa kuburitswa pa46 °C, adiabatic tembiricha inokwira ye6 °C, inofanirwa kunge iri iyo inonangwa yekuita kupisa kuburitswa.Pa 76 °C, pakanga paine kupisa kwakasimba uye kuburitswa kwegasi, izvo zvakakonzera zvakananga tangi rekuyedza kuputika.Zvinoratidzwazve kuti mhinduro haina kukodzera kukwidziridzwa.
HEL nechikwata vakafunga shanduko yepasi, asi DSC bvunzo dzakaratidza kuti kunyangwe kuvapo kwebhesi kwakadzikisa kupisa kwekuparara kwepropargyl doro.
Kuongorora kwekuongorora uchishandisa alkali kwakaratidza kuti maitiro eKOH aive akanaka.Kuongororwazve kwezvinonyungudutsa kwakaratidza kuti dioxane yaive mhinduro iri nani.Miedzo yeARC yakaratidza kuti mushure mekuita kwekusagadzikana kwechinangwa chekuita, tembiricha yakaramba ichikwira kusvika pa200 ° C uye zvakadaro hapana kuora kwakanyanya kwakawanikwa.Chimiro ichi chinogona kukwidziridzwa zvakachengeteka.
