| uses | pesticide intermediates are used to produce insecticides such as imidothion. Used for organic synthesis of pesticides, dyes, pigments, and medicines Used for the amide methylation reaction of aromatic hydrocarbons in trifluoromethanesulfonic acid. |
| production method | is obtained by the reaction of phthalimide and formaldehyde. Add formaldehyde to the reaction pot, add water to mix formaldehyde to a concentration of about 12%. Phthalimide is added under stirring, and the dosage is phthalimide: formaldehyde = 1:1.1 (molar ratio). The finished product is obtained by heating to 98-102 ℃, refluxing reaction 2.5h, cooling to 35 ℃, centrifugal filtration and drying. |
