| Txoj kev tsim khoom |
1-Decanol yog npaj ua lag luam los ntawm kev txo sodium los yog los ntawm kev kub siab catalytic txo cov txiv maj phaub roj, txiv maj phaub fatty acids, los yog esters . Nws kuj yog tsim los ntawm cov txheej txheem Ziegler, uas koom nrog oxidation ntawm trialkylaluminum compounds. |
| Kev npaj |
Los ntawm kev txo sodium los yog high-pressure catalytic hydrogenation ntawm esters ntawm ib txwm tshwm sim capric acid, los yog los ntawm oligomerization ntawm ethylene siv aluminium alkyl technology. |
| Daim ntawv thov |
decyl cawv tuaj yeem siv rau txhua qhov haujlwm, suav nrog ua emollient, ua npuas dej-booster, surfactant thiab viscosity controller, nrog rau daim npog qhov ncauj thiab ua cov tshuaj tsw qab. Decyl cawv tshwm sim nyob rau hauv qab zib txiv kab ntxwv thiab ambrette noob. Nws kuj yog muab los ntawm kev lag luam los ntawm cov kua paraffin. |

| Reactivity Profile |
Decyl cawv tawm tsam plastics. REF [Handling Chemicals Safely, 1980. p. 236] ib. Acetyl bromide reacts hnyav nrog cawv lossis dej, [Merck 11th ed., 1989]. Kev sib xyaw ntawm cov cawv nrog cov concentrated sulfuric acid thiab muaj zog hydrogen peroxide tuaj yeem ua rau tawg. Piv txwv li: Kev tawg yuav tshwm sim yog tias dimethylbenzylcarbinol ntxiv rau 90% hydrogen peroxide ces acidified nrog concentrated sulfuric acid. Kev sib xyaw ntawm ethyl cawv nrog cov concentrated hydrogen peroxide tsim cov khoom tawg muaj zog. Kev sib xyaw ntawm hydrogen peroxide thiab 1-phenyl-2-methyl propyl cawv yuav tawg yog tias acidified nrog 70% sulfuric acid, [Chem. Eng. Xov Xwm 45(43):73(1967); J, Org. Chem. 28: 1893 (1963). Alkyl hypochlorites ua phem heev. Lawv tau yooj yim tau los ntawm reacting hypochlorous acid thiab alcohols nyob rau hauv aqueous tov los yog tov aqueous-carbon tetrachloride daws. Cov tshuaj chlorine ntxiv rau cov cawv yuav zoo ib yam ua rau alkyl hypochlorites. Lawv decompose nyob rau hauv txias thiab tawg ntawm raug tshav ntuj los yog kub. Tertiary hypochlorites tsis ruaj khov dua li theem nrab lossis thawj hypochlorites, [NFPA 491 M, 1991]. Base-catalysed cov tshuaj tiv thaiv ntawm isocyanates nrog cawv yuav tsum tau nqa tawm hauv cov kuab tshuaj inert. Cov kev tshwm sim zoo li no thaum tsis muaj cov kuab tshuaj feem ntau tshwm sim nrog kev ua phem heev, [Wischmeyer(1969)]. |
| Health Hazard |
Kev sib cuag ncaj qha tuaj yeem ua rau qhov muag khaus; tsawg toxicity. |
| 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. |
