Abstract:
ORGANOLEAD COMPOUNDS POSSESS HERBITOXIC PROPERTIES. THEREFORE, FORMULATIONS CONTAINING SUCH COMPOUNDS ARE USEFUL IN CONTROLLING UNDESIRABLE VEGETATION OR IN PLANT DEFOLIATION WITHOUT KILLING THE PLANT ITSELF.
Abstract:
Phenols are alkylated by reaction with primary or secondary alkanols containing two or more carbon atoms in the presence of alkali metal hydroxides at elevated temperatures.
Abstract:
Organic material, especially polypropylene, is stabilized by the additon of mono- or di- (dihydrocarbyl-hydroxyphenyl) alkyl phosphates, phosphites, thiophosphates or thiophosphites, such as 3,5-di-tert-butyl-4-hydroxyphenyl di-n-octadecyl phosphate. Effectiveness is synergistically improved by inclusion of a dialkyl thiodialkanoate such as dilaurylthiodipropionate.
Abstract:
THE REACTION OF PHENOLS UNSUBSTITUTED IN AT LEAST ONE POSITION ORTHO OR PARATO THE HYDROXYL GROUP WITH FORMALDEHYDE AND MONO- OR DIMERCAPTANS YIELDS, RESPECTIVELY, A-(HYDROCARBYLTHIO)-CRESOLA OR A,A''-ALKYLENE DITHIOBIS COMPOUNDS. FOR EXAMPLE, THE REACTION OF 2,6-DI-TERT-BUTYLPHENOL WITH FORMALDEHYDE AND DODECYL MERCAPTAN YIELDS 2,6-DI-TERT-BUTYL-A-(DODECYLTHIO)-P-CRESOL. THE PRODUCTS ARE USEFUL AS ANTIOXIDANTS.
Abstract:
Methylenebis(dicyclopentyl phenols) in which at least one cyclopentyl group is ortho to the phenolic hydroxy group are effective antioxidants in a broad range of organic materials including mineral and synthetic lubricating oil and polyolefins.
