In heterogeneous catalysis, the catalyst is in a different phase from the reactants. 80841-78-7, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 80841-78-7, name is C5H5ClO3. In an article£¬Which mentioned a new discovery about 80841-78-7
To a solution of the compound of Formula IV (5.0 g) in toluene (40 mL), dimethylacetamide (10 mL) is added, followed by addition of sodium hydroxide (1.2 g) and N,N-diisopropylamine (3.7 g) at 25-35C. The mixture is stirred at 40- 45C for 4 hours. 5-Methyl-2-oxo-(1 ,3-dioxolene-4-yl)methyl chloride (1.5 g) and tetrabutylammonium bromide (0.5 g) are added at 40-450C. The mixture is stirred at 60-70C for 8 hours. The mass is cooled to 25-35C, water (50 mL) is added, and the pH is adjusted to about 6-7 by adding 10% aqueous HCI. The layers are separated. The aqueous layer is extracted with toluene (25 mL). The organic layers are combined and washed with water (25 mL). The solvent is distilled under reduced pressure. Methanol (25 mL) is added to the residue. The mixture is cooled to 0-50C and stirred at that temperature for 45 minutes. The formed solid is filtered, washed with methanol (10 mL) and dried for 45 minutes under vacuum (yield 3.0 g).
The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 4-(Chloromethyl)-5-methyl-1,3-dioxol-2-one.C5H5ClO3
