He mea motuhake ki te hanga waipiro propargyl, 1,4 butynediol me te 3-chloropropyne
Wai tino paitini hua pai propargyl alcoho
Whakaahuatanga Hua
Te wai me te haunga karekau me te kakara.Ka uru ki te wai, te waiwaro, te aldehydes, te benzene, te pyridine, te chloroform me etahi atu whakarewa pararopi, he wairewa i roto i te waro tetrachloride, engari karekau e rewa i roto i te waiwaro aliphatic.He ngawari ki te huri kowhai i te wa e tuu ana mo te wa roa, ina koa ka tutaki ki te marama.Ka taea te hanga azeotrope ki te wai, ko te tohu azeotropic he 97 ℃, ko te ihirangi o te waipiro propargyl he 21 2%。 Ka taea te hanga azeotrope me te benzene, ko te tohu azeotropic he 73 ℃, ko te ihirangi o te waipiro propargyl he 13.8%.Ko tana kohu me te hau he ranunga pahū, ka puta te ngingiha me te pahūtanga i te wa e tuwhera ana te ahi me te wera nui.Ka kaha te tauhohenga ki nga waiora.Ki te wera nui, ka puta pea te tauhohenga polymerization me te maha o nga ahuatanga exothermic ka puta, ka pakaru nga ipu me nga aitua pahū.

Ko te waipiro Propargyl e whakamahia nuitia ana i roto i nga hohipera (sulfonamides, fosfomycin sodium, me etahi atu) me te hanga pesticides (propargyl mite).Ka taea te hanga hei aukati waikura mo nga paipa keri me nga paipa hinu i roto i te umanga hinu.Ka taea te whakamahi hei taapiri i roto i te umanga rino hei aukati i te hauwai embrittlement o te maitai.Ka taea te hanga hei whakamarama i roto i te ahumahi hiko.
Ko te waipiro Propargyl he hua matū tino whakarōpūtia me te paitini whakapeka: ld5020mg/kg (whakahaere waha ki te kiore);16mg/kg (rapeti percutaneous);Lc502000mg/m32 haora (whakamohu i roto i te kiore);Ko nga kiore i hongi 2mg/l × 2 haora, ka mate.
Te paitini iti me te roa: te kiore i whakangoatia 80ppm × 7 haora / ra × 5 ra / wiki × I te 89 o nga ra, ka pupuhi te ate me te whatukuhu, ka heke nga pūtau.
