    Abstract: A preparation method of phenylcarboxamides of formula (I), the reaction scheme of which is as follows: wherein the groups are defined in the description. In this method, 3-halo-1-(3-chloro-2-pyridinyl)-4,5-dihydro-1H-pyrazole-5-carboxylic acid esters (V) as the raw materials are hydrolyzed to obtain carboxylic acids of formula (IV) under a basic condition, and carboxylic acids (IV) are simultaneously acyl halogenated and oxidated to get acyl halide of formula (III), and then without the presence of a acid binging agent, acyl chlorides (III) are reacted with substituted anilines (II) to get phenylcarboxamides of formula (I) in high yield.

    Abstract: A drum washing machine is provided with a double spraying system used for washing the window and the window gasket ring respectively. A first spraying nozzle is connected with the inlet solenoid valve of the washing machine to wash the outer surface of the watching window and the window gasket ring, and a second spraying nozzle to wash the folded inner wall of the window gasket ring. The spraying nozzles are connected to the solenoid valve through a three-way pipe, or connected to the solenoid valve of the washing machine through respective pipes. The double spraying system intakes water and soaks the clothes in the washing process, and/or intakes water and sprays the watching window and the window gasket ring simultaneously, and/or sprays the watching window and the window gasket ring when dehydrating the clothes in the dehydrating process.
