There are no grammatical difficulties in this sentence. Crotyl alcohol: also known as 2-butene-1-alcohol; 2-butene-1-OH. Properties: Also referred to as 2-butene-1-alcohol (2-butene-1-OH); CH3CH=CHCH2OH. It has cis (Z) and trans (E) isomers. Liquids with a special odor. The cis boiling point is 123.6°C. Relative density 0.8662, refractive index 1.4342. The trans boiling point is 121.2°C, the relative density is 0.8521, and the refractive index is 1.4288. Soluble in water, and miscible with ethanol and ether. Hydroxyl groups can be oxidized and esterified. Double bonds can undergo addition reactions. Cis is prepared by palladium-catalyzed hydrogenation of 2-butynyl alcohol. For the trans form, crotonaldehyde is used; lithium aluminum hydride. Crotonaldehyde; β-methylacrolin. Properties: CH3CH=CHCHO. Scientific name: β-methylacraldehyde. There are cis and trans isomers. The common commodity is trans-crotonaldehyde. Colorless flammable liquid. It is tear-inducing. It gradually turns light yellow when placed in air or sunlight. Density 0.858. Melting point: -76.5°C, boiling point: 104°C. Slightly soluble in water, soluble in ethanol, ether, benzene, toluene, and gasoline. Chemically reactive. Pure crotonaldehyde tends to resinify. It gradually oxidizes in air to form crotonic acid. Crotonol is formed upon reduction with aluminum isopropoxide. It is used to produce n-butanol, n-butyraldehyde, rubber vulcanization accelerators, alcohol denaturants, and tannins, among other things. It is also used as a warning agent for flue gas. It is formed by the condensation of two molecules of acetaldehyde. This post was last edited by Guan Yue Cang Shu Lou on 2009-2-2 23:29.]
Interestingly, it was shown that the addition of thiophene to the Cu/Al2O3 catalyst enhanced its catalytic activity for the synthesis of crotyl alcohol from crotonaldehyde hydrogenation. The poster should organize it!
Interestingly, the results show that thiophene not only enhances the catalytic activity of Cu/Al2O3 catalysts in the hydrogenation of crotyl alcohol to crotonaldehyde. To put it in order: Interestingly, the results show that the addition of thiophene to the Cu/Al2O3 catalyst enhances the catalytic activity for the hydrogenation of crotonaldehyde to crotonol. If you can solve it yourself, why ask someone else?
Interestingly, it was shown that the addition of thiophene to the Cu/Al2O3 catalyst enhanced the catalytic activity for the synthesis of crotyl alcohol from crotonaldehyde hydrogenation. Interestingly, experiments have shown that thiophene with a Cu/Al2O3 catalyst added can enhance the catalytic activity of the hydroreduction reaction of crotonaldehyde, thereby producing crotonol
Interestingly, experiments have shown that thiophene added to the Cu/Al2O3 catalyst can enhance the catalytic activity of the synthesis reaction in which crotonaldehyde is hydrogenated to crotonol.
