Taw qhia
pent-4-ynoic acid, tseem hu ua pent-4-ynoic acid, tshuaj formula C5H6O2. Cov hauv qab no yog cov lus qhia txog qhov xwm txheej, kev siv, kev tsim thiab kev nyab xeeb cov ntaub ntawv ntawm pent-4-ynoic acid:
Xwm:
- pent-4-ynoic acid yog cov kua tsis muaj xim nrog cov ntxhiab tsw.
-Nws txheeb ze molecular mass yog 102.1g/mol.
Siv:
- pent-4-ynoic acid yog ib qho tseem ceeb nruab nrab ntawm cov tshuaj synthesis thiab yog siv los npaj lwm cov tebchaw.
-Nws tuaj yeem siv rau cov tshuaj tiv thaiv carbonylation, cov tshuaj tiv thaiv condensation thiab esterification cov tshuaj tiv thaiv hauv cov tshuaj tiv thaiv kab mob.
- pent-4-ynoic acid kuj tseem siv tau rau hauv kev npaj tshuaj, tshuaj tsw qab thiab dyes.
Txoj Kev Npaj:
-Kev npaj ntawm pent-4-ynoic acid tuaj yeem ua tiav los ntawm 1-chloropentyne thiab acid hydrolysis. Ua ntej, 1-chloropentyne yog reacted nrog dej los muab cov coj aldehyde los yog ketone, thiab ces cov aldehyde los yog ketone hloov dua siab tshiab rau pent-4-ynoic acid los ntawm oxidation cov tshuaj tiv thaiv.
Cov ntaub ntawv kev nyab xeeb:
- pent-4-ynoic acid yog ib qho tshuaj lom neeg uas tuaj yeem ua rau khaus thiab mob ntawm daim tawv nqaij thiab qhov muag.
- Hnav hnab looj tes tiv thaiv, tsom iav, thiab cov khaub ncaws kuaj thaum siv pent-4-ynoic acid.
-Thaum ntsib daim tawv nqaij lossis qhov muag, yaug tam sim ntawd nrog dej kom ntau thiab nrhiav kev kho mob.
-Tsis txhob sib cuag nrog cov oxidants, muaj zog acids thiab cov hauv paus muaj zog thaum khaws cia thiab siv kom tsis txhob muaj kev phom sij txaus ntshai.
Thov nco ntsoov tias ua ntej siv cov tshuaj, koj yuav tsum nyeem cov ntaub ntawv kev nyab xeeb (MSDS) ntawm cov tshuaj ua tib zoo thiab ua raws li cov txheej txheem kev khiav hauj lwm kom raug thiab cov txheej txheem ua haujlwm zoo.
