Beschreibung
Zusammenfassung:	The invention relates to derivatives of para-chloro-ortho-sulphonamide-phenoxyacetic acid used as growth stimulators in plants and to a process for preparing the same. According to the invention, the derivatives are the 2[(4''-methyl-piperidino)-sulphonyl]-4-chloro-phenoxyacetic acid and the 2-(piperidino-sulphonyl)-4-chloro-phenoxyacetic acid. As claimed by the invention, the process consists of the hydrolysis reaction of the ethyl esters of the para-chloro-ortho-sulphonamide-phenoxyacetic acid in a basic medium, at an ester : NaOH molar ratio of 1 : 2.5 at reflux, for 1 h. Invenţia se referă la derivaţi ai acidului para-clor-orto-sulfonamido-fenoxiacetic şi la un procedeu pentru prepararea acestora, utilizaţi ca stimulatori de creştere la plante. Derivaţii conform invenţiei sunt acidul 2[(4"-metil-piperidino)-sulfonil]-4-clor-fenoxi acetic şi acidul 2-(piperidino-sulfonil)-4-clor-fenoxi acetic. Procedeul conform invenţiei constă din reacţia de hidroliză a esterilor etlici ai acidului para-clor-orto-sulfonamido-fenoxiacetic în mediu bazic, la un raport molar între ester:NaOH de 1:2,5 la reflux, timp de 1 h.
