    Abstract: An antidegradant composition, an antidegradant master batch comprising the antidegradant composition and a rubber composition comprising the antidegradant composition or the antidegradant master batch. The antidegradant composition comprises antidegradant TMPPD and one or two selected from antidegradant N3100-B and an antidegradant N3100-C. The antidegradant composition and antidegradant master batch render a rubber compound and a rubber article excellent discoloration resistance, fatigue resistance, ozone resistance, and mechanical properties before and after thermal oxidative aging and enables the rubber compound to be used in the manufacture of all or part of the rubber matrix, especially as a tire sidewall rubber composition and a tire tread rubber composition.

    Abstract: A formulation for rubber composition with reduced odor and good thermal oxidative aging-resistance and tension fatigue resistance comprising 100 parts by weight of a diene elastomer, 30 to 70 parts by weight of a reinforcing filler, 0.1 to 8 parts by weight of an antidegradant composition, and 0.5 to 3 parts by weight of a crosslinker, wherein the antidegradant composition includes a 6PPD antidegradant with a purity of equal to or greater than about 98%and an S-TMQ. The rubber composition has no added odor inhibitor/adsorbent or deodorizing additive, while by using combination of a 6PPD antidegradant with purity of equal to or greater than about 98%and an S-TMQ instead of traditional combination of a 6PPD antidegradant and a TMQ antidegradant, the VOC emission of the rubber composition is effectively reduced, the odor grade is reduced, and the thermal oxidative aging-resistance and tension fatigue resistance is improved.

    Abstract: Novel and long-acting rubber anti-degradant and rubber composition comprising the same for tires. The anti-degradant comprises at least two compounds, each of which is selected from a compound of Formula I, II, III-a, or III-b: and each of the compounds have different formulae from others, and can't be compounds of formula III-a and III-b at the same time when the anti-degradant consists of only 2 compounds. The anti-degradant is used to provide a rubber composition with improved long-term resistance to thermo-oxidative aging and ozone aging.

    Abstract: A method for preparing methyl isobutyl ketone comprises reacting mesityl oxide and methyl isobutyl alcohol under the action of a copper-based catalyst to produce methyl isobutyl ketone, where mesityl oxide and methyl isobutyl alcohol are employed to carry out hydrogen in-situ transfer under the action of the copper-based catalyst, and methyl isobutyl ketone is prepared in one step. The entire reaction process does not require an external hydrogen system. The reaction is carried out under normal pressure, and the process flow is short. The reaction has high atom utilization, high safety, and is suitable for popularization and industrial application.

    Abstract: A method for preparing an aryl substituted p-phenylenediamine substance is provided. A structural formula of the aryl substituted p-phenylenediamine substance is shown as Formula (I′), where each of R′ and R″ is phenyl or o-methylphenyl, and R′ is same as or different from R″; and the method comprises that: a raw material A and a raw material B are reacted in the presence of a hydrogen acceptor and a catalyst to form the aryl substituted p-phenylenediamine substance, the raw material A having a structure shown as Formula (I), the raw material B being cyclohexanone and/or o-methylcyclohexanone and the hydrogen acceptor being a hydrogen acceptor capable of accepting hydrogen for conversion into the raw material B. Raw materials are low in cost and readily available; use of a large amount of water for post-treatment is avoided. The reaction condition is relatively mild, and corrosion to equipment is avoided.
