Adding a certain compound to certain chemical reactions, such as: 34846-90-7, name is Methyl 3-methoxyacrylate, belongs to esters-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 34846-90-7, Recommanded Product: 34846-90-7
Example 2 The toluene solution of 3-mercapto-2-butanone from the previous step (613 g of ca. 25 wtpercent solution) was placed in a clean, dry reactor along with 15 g of methyl-3-methoxyacrylate. The mixture was warmed to 25°C, stirred vigorously, and treated with solid sodium methoxide (8.5 g, ca. 0.1 equiv.) all at once. The remaining methyl-3-methoxyacrylate (151 g) was added in at a rate to keep the temperature at or below 35°C (2 h). The resulting mixture was allowed to reach room temperature and stir for 21 h. Concentrated hydrochloric acid (88 g) was added to the mixture over 30 min such that the temperature did not exceed 35°C. The resulting mixture was stirred vigorously for 2 h, then treated with 73 g of water, and stirred for 10 min more. The phases were allowed to separate. After standing for 10 min, the aqueous phase was drained from the reactor, and the upper, product phase was washed with 100 g of 5percent sodium bicarbonate solution. After being stirred for 15 min, the phases were allowed to separate. The lower, aqueous phase was drained from the reactor, and the upper. product phase was transferred to a distilling flask. The toluene was distilled through a 5-plate distillation column at 13.3 kPa [100 mmHg]. After a small fraction containing toluene and other low boiling impurities was collected, the product, 3-carbomethoxy-4,5-dimethylthiophene, was distilled through the column at 6.665 kPa [150 mmHg].
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Methyl 3-methoxyacrylate, other downstream synthetic routes, hurry up and to see.
