A six-centered unimolecular elimination reaction that yields ethylene and methyl ethanoate (methyl acetate) was added (Fig. 7) with an activation energy of 68 kcal mol−1 [225]. However, the authors found that this last pathway (Fig. 7) contributed very little (<1%) to MB decomposition ...

Furthermore, the Ba/γ-Ti–Al2O3 catalyst demonstrated excellent catalytic performance, with a methyl acetate conversion rate of 50% and methyl acrylate selectivity up to 90.2%. Compared with the Ba/Al2O3 catalyst, the Ba/γ-Ti–Al2O3 catalyst had better catalytic activity, stability and ...
In brief, 0.3 g of each sample was spiked with recovery standard and extracted four times with 10 mL of a 1:1 (v:v) n-hexane and ethyl acetate solvent mixture in an ultrasonic bath at room temperature for 20 min. Samples were then centrifuged for 10 min at 3000 rpm to separate the...
Samples were diluted tenfold in ultrapure water, filtered through a 0.22 µm cellulose acetate filter and diluted eightfold for the initial conditions used for LC/MS. PABA was quantified using UPLC (UPLC Ultimate 3000) equipped with an ethylene-bridged hybrid amide UPLC column (Aquity UHPLC...
The mixture was then cooled to room temperature, quenched by adding five drops of H2O and then diluted by ethyl acetate (EtOAc, 30 mL). The obtained solution was dried over anhydrous Na2SO4. After filtration and concentration by rotary evaporation, the residue was purified by silica gel ...
High-molecular-weight compounds which may be mentioned are: poly(methylmethacrylate), copolymers of (meth)acrylic acid esters and (meth)acrylic acid, styrene-maleic anhydride copolymers, poly(vinyl acetate), acetalized poly(vinyl alcohol)s, copolymers of vinyl acetate and N-vinylpyrrolidone, and ...
Pure ethyl acetate was used as eluent for 1 and 4; ethyl acetate/pentane: 4:6 for 3 and 6. Method B: a solution of DPI (74 mg, 0.6 mmol) and GMF (288 mg, 1.0 mmol) in water (1.0 mL) was treated with 2-cyclopenten-1-one (164 mg, 2.0 mmol) or 2-cyclohexen-1-one (123 ...
