2-Ethylhexanal yog siv los ua ib qho nruab nrab rau cov tshuaj synthesis?thiab hauv kev tsim tshuaj thiab tshuaj tsw qab. |
| Siv |
2-Ethylhexanal tuaj yeem siv los ua tus qauv tshuaj ntsuam xyuas rau kev txiav txim siab ntawm cov tshuaj ntsuam xyuas hauv huab cua ntawm cov nroj tsuag charcoal los ntawm kev ua haujlwm siab ua kua chromatography thiab kuaj pom UV. Nws kuj tseem siv tau los ua tus qauv sab hauv rau kev txiav txim siab ntawm cov tshuaj ntsuam xyuas los ntawm cov ntoo pellets (6) los ntawm cov txheej txheem chromatography. |

| Reactivity Profile |
2-ETHYLHEXANAL yog aldehydes. Aldehydes feem ntau koom nrog hauv tus kheej-condensation lossis polymerization cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv no yog exothermic; Lawv feem ntau catalyzed los ntawm acid. Aldehydes tau nkag siab oxidized los muab carboxylic acids. Cov nplaim hluav taws kub thiab / lossis cov pa phem yog tsim los ntawm kev sib xyaw ntawm aldehydes nrog azo, diazo tebchaw, dithiocarbamates, nitrides, thiab muaj zog txo cov neeg ua haujlwm. Aldehydes tuaj yeem cuam tshuam nrog huab cua los muab thawj peroxo acids, thiab thaum kawg carboxylic acids. Cov tshuaj autoxidation no tau qhib los ntawm lub teeb, catalyzed los ntawm cov ntsev ntawm cov hlau hloov pauv, thiab yog autocatalytic (catalyzed los ntawm cov khoom ntawm cov tshuaj tiv thaiv). Qhov sib ntxiv ntawm stabilizers (antioxidants) rau kev xa khoom ntawm aldehydes retards autoxidation. |
| Hazard |
Ignites hauv huab cua. |
| Health Hazard |
Inhalation tej zaum yuav irritating mucous daim nyias nyias; overexposure yuav ua rau kiv taub hau thiab vau. Kev noj haus ua rau khaus ntawm qhov ncauj thiab plab. Kev sib cuag nrog qhov muag lossis tawv nqaij ua rau khaus. |
| Hluav Taws Xob |
HIGHLY FLAMMABLE: Yuav tau yooj yim ignited los ntawm tshav kub, sparks los yog nplaim taws. Cov vapors tuaj yeem tsim cov khoom tawg nrog cua. Vapors tuaj yeem mus rau qhov chaw ntawm qhov hluav taws kub thiab rov qab flash. Feem ntau cov vapors hnyav dua li huab cua. Lawv yuav kis tau mus rau hauv av thiab sau rau hauv qhov chaw qis lossis qhov chaw kaw (sewers, hauv qab daus, tanks). Vapor explosion txaus ntshai nyob hauv tsev, sab nraum zoov lossis hauv cov kav dej. Cov dej ntws mus rau hauv cov kav dej yuav ua rau muaj hluav taws kub lossis tawg. Cov thawv ntim khoom tuaj yeem tawg thaum cua sov. Cov kua dej ntau yog sib dua li dej. |
