    摘要： Pentaerythritol co-esters derived from pentaerythritol, (3-alkyl-4-hydroxyphenyl)-alkanoic acids and alkylthioalkanoic acids or lower alkyl esters of such acids are useful as stabilizers of organic material normally susceptible to oxidative and/or thermal deterioration. The co-esters are advantageously prepared by transesterification of such esters with pentaerythritol. Preferred co-esters are (I) pentaerythritol tris[3-(3,5-di-tert-butyl-4-hydroxylphenyl)propionate]-mono[3-n-dodecylthiopropionate] and (II) pentaerythritol bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]-bis[3-n-dodecylthiopropionate]. The co-esters are especially useful in stabilizing applications for which physical mixtures of (i) (3-alkyl-4-hydroxyphenyl)alkanoic acid esters of polyols with (ii) polyalkanol esters of alkylthioalkanoic acids have heretofore been proposed.

    摘要： The invention relates to new diphenyl ethers of the general formula ##STR1## wherein X is a hydrogen atom, a halogen atom, a nitro group, an optionally halogenated alkyl, alkoxy or alkylthio group having 1-6 carbon atoms, or an alkanoyl group having 1-4 carbon atoms;Y is a nitrogen atom or a group of the formula CH or CCl;Z is a hydrogen atom, a halogen atom, a nitro group, an optionally halogenated alkyl group having 1-4 carbon atoms, or an alkanoyl group having 1-4 carbon atoms; n is 0-2;R.sub.1 is a hydrogen atom, or an alkyl or alkanoyl group having 1-4 carbon atoms;R.sub.2 and R.sub.3 are equal or different and represent hydrogen atoms or alkyl groups having 1-4 carbon atoms; andA is a group of the general formula ##STR2## wherein R.sub.4 is a hydrogen atom, an alkyl group having 1-6 carbon atoms, or a cation of an alkali metal, alkaline earth metal or an alkylated or non-alkylated ammonium group, andR.sub.5 and R.sub.6 are equal or different and represent hydrogen atoms, dialkylamino groups wherein the alkyl groups each have 1-4 carbon atoms, alkyl groups having 1-4 carbon atoms, or wherein R.sub.5 and R.sub.6 together with the nitrogen atom to which they are bound can form a heterocyclic ring which may comprise a second hetero atom selected from O, S or N;with the provisos, that X and Z are not both hydrogen atoms or nitro groups, and that if A is a group of the formula OR.sub.4 R.sub.1 is not an alkyl group.The compounds have a herbicidal activity. After having been processed to compositions, the compounds may be used for controlling undesired plants or for leaf-desiccation in agricultural and horticultural crop in a dosage from 0.01 to 5 kg of active substance per hectare.
