Nhanganyaya
Ethyl ethynyl carbinol(Ethyl ethynyl carbinol) inhengo yeorganic ine kemikari formula C6H10O. Inowanikwa nekuwedzera hydroxyl boka (OH boka) kune pentyne. Zvimiro zvayo zvemuviri ndezvizvi:
Ethyl ethynyl carbinol imvura isina ruvara uye inonhuwa. Inonyungudika mumvura uye yakawanda organic solvents senge doro, ethers uye esters. Iine density yakaderera, yakareruka pane mvura, uye ine painofashaira yakakwira.
Ethyl ethynyl carbinol ine zvimwe zvekushandisa mune organic synthesis. Inogona kushandiswa sechinhu chekutanga uye chepakati mune organic synthesis, uye inowanzoshandiswa mukugadzira carbonyl-ine makomisheni. Inogona kutora chikamu mualkyd esterification, olefin yekuwedzera, saturated hydrocarbon carbonylation reaction. Mukuwedzera, 1-pentin-3-ol inogonawo kushandiswa mukugadzirwa kwedhayi nemishonga.
Nzira yekugadzirira Ethyl ethynyl carbinol inogona kuitwa nematanho anotevera: kutanga, pentyne uye sodium hydroxide (NaOH) inobatwa mu ethanol kuti ibudise 1-pentyn-3-ol sodium munyu; zvino, 1-pentyn-3-ol sodium munyu inoshandurwa kuita Ethyl ethynyl carbinol munyu ne acidification reaction.
Paunenge uchishandisa uye kubata Ethyl ethynyl carbinol, unofanirwa kuterera kune inotevera chengetedzo ruzivo: Inotsamwisa uye inogona kukonzera kutsamwa uye kukuvadza paganda nemeso, saka iwe unofanirwa kupfeka zvakakodzera zvekuzvidzivirira nazvo, senge magirovhosi uye magirazi. Mukuwedzera, inopfuta uye inofanira kudzivirirwa kubva pakusangana nemoto wakazaruka kana nzvimbo dzekushisa dzepamusoro, uye dzakachengetwa zvakanaka. Chero kumwe kubata kana kuchengetedza kwakabatana nekomboniti kunofanirwa kuitwa maererano nemaitiro akachengeteka ekushanda.
