Usage

General Description

4,4'-METHYLENEBIS(2-TERT-BUTYL-6-METHYLPHENOL), also known as MBTBP, is a chemical compound commonly used as an antioxidant in various industrial applications. It is a hindered phenolic antioxidant that helps protect materials and products from oxidative degradation, thereby extending their shelf life and stability. MBTBP is insoluble in water but soluble in organic solvents, making it suitable for use in plastics, rubber, and other polymer-based materials. It is also used in lubricants, adhesives, and coatings to improve their resistance to degradation caused by exposure to heat, light, and oxygen. Additionally, MBTBP is known for its low volatility and high thermal stability, making it a valuable additive in the production and preservation of a wide range of industrial and consumer goods.

γ-hydroxypropylation of 2,6-dialkyl(aryl)phenols with allyl alcohol and its derivatives

The composition of the products of the reaction of 2,6-disubstituted phenols with allyl alcohol and its derivatives in an alkaline medium was investigated, the conditions for carrying out the reaction with the predominant formation of 4-(3-hydroxypropyl)-2,6-dialkyl(aryl)phenols were found, and its mechanism was suggested. The reaction was examined on an industrial scale. An important result is the practical demonstration of alkaline catalysis performed under homogeneous conditions with participation of phenols, when the used alkaline catalyst is recovered in the process without the formation of waste waters.

Lubricant composition

A composition comprising a) a lubricant or a hydraulic fluid and b) at least one compound of the general formula I STR1 in which x=1 or 2 and, if x=1, R is as defined for R1 or R3 --O-- or, if x=2, R is as defined for R8, and R1 and R3 are, for example, alkyl, cycloalkyl, alkenyl, phenyl, naphthyl, aralkyl or alkaryl, or alkyl, cycloalkyl, alkenyl, phenyl, naphthyl, aralkyl or alkaryl, which are monosubstituted or polysubstituted by groups from the series comprising halogen, cyano, nitro, e.g. --OCH3 or e.g. --COOCH3, or alkyl, cycloalkyl, alkenyl, aralkyl or alkaryl which are interrupted by one or more groups from the series comprising --O--, --S--, --NH--, STR2 or alkyl, cycloalkyl, alkenyl, aralkyl or alkaryl which are monosubstituted or polysubstituted by groups from the series comprising halogen, cyano, nitro, e.g. --OCH3 or e.g. --COOCH3 and interrupted by one or more groups from the series comprising --O--, --S--, --NH--, STR3 and R2 is NR4 R5, --OR6 or --SR7, and R4 and R5 are identical or different and are, for example, --H, alkyl, phenyl, naphthyl, aralkyl or alkaryl, or R4 and R5, together with the N atom linking them, form, for example, a piperidine or morpholine radical, and R6 and R7 can be alkyl which may be interrupted by one or more groups from the series comprising --O--, --S--, --NH--, STR4 or are, for example, phenyl, naphthyl, alkaryl or aralkyl, and R8 can be alkylene which may be interrupted by at least one --O-- group or alkylidene which may be interrupted by at least one --O-- group. Some of the compounds of the formula I are novel. The compositions show an improved stability towards oxidative degradation, confer protection under extreme pressures and reduce frictional wear.

Non-migrating 1-hydrocarbyloxy-2,2,6,6-tetramethylpiperidine 1,3,5-triazine derivatives

1-Hydrocarbyloxy-2,2,6,6-tetramethylpiperidine derivatives of s-triazines having functional groups such as hydroxy, amino, carboxy, epoxy, isocyanate or the like present are capable of chemically bonding with polymer substrates having anhydride, epoxide, alkoxymethylmelamine or isocyanate moieties present. This chemical bonding prevents migration or loss of the stabilizer during subsequent processing or end-use application of the stabilized polymer.
