1 1-Bis (Hydroxymethyl) Cyclopropane (CAS#)39590-81-3) Taw qhia
2. Melting point: -33 ° C
3. Kub taw tes: 224 ° C
4. Ceev: 0.96 g / mL
5. Solubility: Soluble nyob rau hauv dej, cawv thiab ether solvents.
1,1-CYCLOPROPANE DIMETHANOL yog raws li nram no:1. Siv los ua cov kuab tshuaj rau cov organic synthesis: Vim nws cov solubility thiab reactivity, nws tuaj yeem siv los ua cov kuab tshuaj los pab cov tshuaj tiv thaiv.
2. rau cov synthesis ntawm catalysts: yuav siv tau raws li raw cov ntaub ntawv rau kev npaj ntawm catalysts.
3. Siv los ua surfactant: Hauv qee cov ntawv thov kev lag luam, nws tuaj yeem siv ua surfactant rau emulsification thiab dispersion.
Kev npaj ntawm 1,1-CYCLOPROPANE DIMETHANOL feem ntau yog tau los ntawm reacting cyclopropane thiab chloroform nyob rau hauv lub xub ntiag ntawm ib tug catalyst. Cov kauj ruam tshwj xeeb yog raws li hauv qab no:
1. Ntxiv cyclopropane thiab chloroform rau cov hlab ntsha cov tshuaj tiv thaiv nyob rau hauv ib qho molar ratio.
2. ntxiv cov catalyst, feem ntau siv catalysts xws li hlau palladium thiab trimethyl boron oxide.
3. Cov tshuaj tiv thaiv yog nqa tawm nyob rau hauv qhov kub thiab txias tsis tu ncua, thiab yuav tsum tau siv sij hawm ntev dua nyob rau hauv chav tsev kub.
4. Tom qab qhov kawg ntawm cov tshuaj tiv thaiv, 1,1-CYCLOPROPANE DIMETHANOL cov khoom tau txais los ntawm cov kauj ruam ntawm distillation thiab purification.
Yog xav paub txog kev nyab xeeb ntawm 1,1-CYCLOPROPANE DIMETHANOL, thov nco ntsoov cov hauv qab no:
1. 1,1-CYCLOPROPANE DIMETHANOL yog corrosive rau ib qho twg, yog li yuav tsum tau zam ntawm daim tawv nqaij thiab qhov muag. Yog tias kis tau, yaug tam sim nrog dej ntau thiab nrhiav kev pab kho mob.
2. Thaum siv los yog khaws cia, tsis txhob sib cuag nrog cov oxidants thiab acidic tshuaj kom tsis txhob muaj kev phom sij txaus ntshai.
3. tsis txhob nqus pa ntawm nws cov vapor, yuav tsum nyob hauv qhov chaw ua haujlwm zoo.
4. Nws raug nquahu kom hnav cov khoom tiv thaiv tsim nyog, xws li hnab looj tes thiab tsom iav.
