Nyanzvi mukugadzira propargyl doro, 1,4 butynediol uye 3-chloropropyne.
Yakanyanya muchetura mvura yepamusoro chigadzirwa propargyl doro
Product Description
Liquid ine mhepo inoputika uye inonhuwa.Inosanganiswa nemvura, ethanol, aldehydes, benzene, pyridine, chloroform uye zvimwe organic solvents, zvishoma soluble mucarbon tetrachloride, asi isinganyunguriki mualiphatic hydrocarbons.Zviri nyore kuita yero kana yaiswa kwenguva yakareba, kunyanya kana yasangana nechiedza.Inogona kuumba azeotrope nemvura, iyo azeotropic point i97 ℃, uye zviri mupropargyl doro i21 2%. Inogona kuumba azeotrope ne benzene, iyo azeotropic point i73 ℃, uye zviri mupropargyl doro i13.8%.Mhepo yaro nemhepo zvinoumba musanganiswa unoputika, unogona kukonzera kupisa uye kuputika kana moto wakazaruka uye kupisa kwakanyanya.Inogona kuita zvakasimba neoxidants.Kana paine kupisa kwakanyanya, kuita kwepolymerization kunogona kuitika uye huwandu hukuru hweexothermic phenomena inogona kuitika, zvichikonzera kuputika kwemudziyo uye tsaona yekuputika.

Propargyl doro rinoshandiswa zvakanyanya muzvipatara (sulfonamides, fosfomycin sodium, nezvimwewo) uye kugadzirwa kwemishonga yezvipembenene (propargyl mite).Inogona kugadzirwa kuita corrosion inhibitors yemapombi ekuchera uye pombi dzemafuta muindasitiri yepetroleum.Inogona kushandiswa sechinhu chinowedzera muindasitiri yesimbi kudzivirira hydrogen embrittlement yesimbi.Inogona kugadzirwa kuva inopenya muindasitiri ye electroplating.
Propargyl doro ndeye yakasarudzika yakasarudzika kemikari chigadzirwa chine acute toxicity: ld5020mg/kg (kudzorwa nemuromo kumakonzo);16mg/kg (tsuro percutaneous);Lc502000mg/m32 maawa (kufema mumakonzo);Mbeva dzakafema 2mg/l × maawa maviri, dzinouraya.
Subacute uye chisingaperi chepfu: makonzo akafemerwa 80ppm × 7 maawa / zuva × 5 mazuva / vhiki × Pazuva re89th, chiropa neitsvo zvakazvimba uye masero akadzikira.
