Product Description

Txoj kev npaj: Nws yog tau los ntawm reacting propargyl cawv nrog phosphorus trichloride.Ua ntej, hluav taws roj thiab phosphorus trichloride yog ntxiv rau hauv cov tshuaj tiv thaiv qhuav, thiab sib tov ntawm propagyl cawv thiab pyridine yog ntxiv dropwise hauv qab 20 ℃.Tom qab ntxiv, nws yog rhuab rau reflux.Tom qab cov tshuaj tiv thaiv rau 4 teev, nws yog ntxiv rau hauv dej khov rau cais cov dej txheej.Cov roj txheej yog ntxiv nrog sodium carbonate dej qhov rais rau ph = 5-6 cais cov dej txheej, thiab tom qab ntawd ntxuav, qhuav thiab distilled nyob rau hauv ib txwm siab kom sau 52-60 ℃ feem kom tau cov khoom tiav.

Cia:khaws cia rau hauv ib qho chaw txias thiab ventilated warehouse.Khaws kom deb ntawm qhov hluav taws kub thiab qhov cua sov.Tiv thaiv los ntawm tshav ntuj ncaj qha thiab khaws cov ntim ntim kaw.Kev tawg pov thawj teeb pom kev zoo thiab qhov cua qhov chaw yuav tsum tau txais yuav.Nws yog txwv tsis pub siv cov cuab yeej siv tshuab thiab cov cuab yeej uas yooj yim los tsim cov txim taws.Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm txheej ceev thiab cov khoom siv tau txais tsim nyog.

Lub hom phiaj:Nws yog siv rau hauv kev tsim cov tshuaj youjiangning, av fumigant, thiab lwm yam. Nws kuj yog ib qho kev hloov kho rau engineering plastics.Nws cov ntsev trisodium yog ib qho zoo heev thaum tshav kub kub stabilizer rau PVC, thiab nws cov esters kuj tseem ceeb additives rau polymers.

Cov txheej txheem tsim khoom chlorpropargyne tau txais los ntawm peb lub tuam txhab yog kev tsim cov chlorpropargyne los ntawm propargyl cawv thiab thionyl chloride raws li kev txiav txim ntawm DMF.Txoj kev no muaj cov kauj ruam yooj yim, ib txoj kev hloov pauv ntawm propargyl cawv yog 100%, thiab DMF ua kom cov kev ncig tsis poob, tsis muaj lwm yam ntxiv, nrog cov txheej txheem luv luv thiab cov khoom siv tsawg dua.Nyob rau tib lub sij hawm, nws realizes nruam ntau lawm.Nws yog thawj cov txheej txheem tshuaj rau kev tsim khoom txuas ntxiv ntawm chlorpropargyne hauv Suav teb

Yav dhau los: daj ntseg daj kua kua 1,4-butynediol

Tom ntej: Cov tshuaj lom neeg ua kua zoo tshaj cov khoom lag luam propargyl cawv
