<p>3',4'-Dichloro-propionanilide, which is known and has the formula <IMAGE> is obtained by reacting 3,4-dichlorophenyl isocyanate with propionic acid in the absence of inert organic solvents at temperatures between 130 DEG C and 160 DEG C. It has already been known for a long time that 3',4'-dichloro-propionanilide has, for example, valuable herbicidal properties and can be used, in particular, for controlling weeds in rice crops.</p> |
