The invention is a process for obtaining membranes having improved selectivity and recovery using a combination of heat treating and UV irradiation.

Membranes having improved selectivity and recovery, and process for

The present invention is directed to novel substituted aniline compounds, the optically active isomers of said compounds, compositions containing said compounds, and the use of these compounds in the selective kill and control of grassy weeds in the presence of valuable crop plants, especially corn plants.

Haloalkoxy anilide derivatives of 2-4(-heterocyclic oxyphenoxy)alkanoic

2-(Phenoxy or phenylthio)-2-(pyrimidinyloxy or 1,3,5-triazinyloxy)alkanoic acid compounds, such as ethyl 2-(2-fluorophenoxy)-2-(4,6-dimethylpyrimidin-2-yloxy)-acetate, were prepared by the reaction of a phenol or thiophenol compound with a 2-chloro-2-(pyrimidinyloxy or 1,3,5-triazinyloxy)alkanoate ester compound or by the reaction of a pyrimidinol or 1,3,5-triazinol with a 2-bromo-2-(phenoxy or phenylthio)alkanoate ester. These compounds, and, especially, agriculturally acceptable salts, esters, and amides of these compounds, were found to have herbicidal utility.

Herbicidal 2-(phenoxy or phenylthio)-2-(,3,5-triazinyloxy) alkanoic acids

Derivatives of 4-((aryloxy)phenoxy)alkenols, their preparation and use as active herbicides for the postemergent control of grassy weeds and especially the control of said weeds in the presence of corn plants are disclosed.

Derivatives of 4-((aryloxy)phenoxy)alkenols and their herbicidal uses

2-(Phenoxy or phenylthio)-2-(pyrimidinyloxy or 1,3,5-triazinyloxy)alkanoic acid compounds, such as ethyl 2-(2-fluorophenoxy)-2-(4,6-dimethylpyrimidin-2-yl-oxy)acetate, were prepared by the reaction of a phenol or thiophenol compound with a 2-chloro-2-(pyrimidinyloxy or 1,3,5-triazinyloxy)alkanoate ester compound or by the reaction of a pyrimidinol or 1,3,5-triazinol with a 2-bromo-2-(phenoxy or phenylthio)alkanoate ester. These compounds, and, especially, agriculturally acceptable salts, esters, and amides of these compounds, were found to have herbicidal utility.

Herbicidal 2-(phenoxy or phenylthio)-2-(pyrimidinyloxy or

4-((Aryloxy)phenoxy)alkenols, their preparation and use as active herbicides for the postemergent control of grassy weeds. The compounds also are useful as intermediates for the preparation of herbicidal derivatives, which compounds are especially useful for the control of grassy weeds in the presence of corn plants.

4-((aryloxy)phenoxy)alkenol as intermediates and herbicides

Compounds of the class comprising (quinolinyl and quinoxalinyloxy)phenoxy) alkenols, e.g., 4-(4-((6-chloro-2-quinolinyl)oxy)phenoxy)-2-penten-1-ol; and a method of preparation, comprising reacting an appropriately substituted quinoline or quinoxaline, e.g., 2,6-dichloroquinoline, with a phenolic substituted pentenol, e.g., 4-(4-hydroxyphenoxy)-2-penten-1-ol, in the presence of a base and organic solvent under an inert atmosphere with or without heat, and then recovering the product. These compounds are useful as intermediates for preparing various known herbicidal compounds and are useful in their own right as post-emergent herbicides for controlling grassy weeds in the presence of corn plants.
