Usage

General Description

6,6'-Methylenedi-2,4-xylenol, also known as MMBZ, is a chemical compound used as an antioxidant and intermediate in the production of various industrial products. It is a white crystalline solid that is insoluble in water but soluble in organic solvents. MMBZ is commonly used in the production of rubber, plastics, and other polymers to improve their stability and resistance to degradation from heat, oxygen, and light. It is also used as an additive in lubricants, adhesives, and coatings to improve their performance and longevity. Additionally, MMBZ has applications in the production of pharmaceuticals and as a stabilizer in the manufacturing of synthetic fibers. However, it is important to handle MMBZ with caution, as it can be harmful if ingested or comes into contact with the skin or eyes.

Lignin-based diphenylmethane diisocyanate as well as preparation method and application thereof

The invention discloses a lignin-based diphenylmethane diisocyanate and a preparation method and application thereof. As shown in Formula I, the lignin-based diphenylmethane diisocyanate is prepared by reacting a lignin-cracking monomer compound II with a carbonyl compound to give compound III, compound III reacts with chloroacetyl ammonia to obtain compound IV, compound IV is subjected Smiles rearrangement reaction to obtain compound V, and compound V is reacted with a compound containing carbon-containing acid to obtain the lignin-based diphenylmethane diisocyanate shown in formula I. The product replaces MDI for synthesis of polyurethane materials, and the toughness of the polyurethane material is improved. Thermal stability and glass transition temperature. When being applied to polyurethane waterproof coating, the water absorption rate is obviously reduced, and the stability of the coating is improved.

Highly sulfonated graphene and graphene oxide nanosheets as heterogeneous nanocatalysts in green synthesis of bisphenolic antioxidants under solvent free conditions

Sulfonated functionalized graphene and graphene oxide nanosheets were prepared via chemical approaches and their catalytic activities were investigated in the green synthesis of 6,6′-(arylmethylene) bis(2,4-dialkylphenol) antioxidants. In this research, three types of the catalysts including sulfonated reduced graphene oxide nanosheets (catalyst 1a), sulfonated graphene oxide nanosheets (catalyst 1b), and sulfonated propylsilane graphene oxide nanosheets (catalyst 1c) were synthesized and used in the synthesis of target molecules. The catalysts were characterized by field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, X-ray diffraction spectroscopy (XRD), and back acid-base titration. The catalyst 1a showed excellent catalytic activity in the green synthesis of 6,6′-(arylmethylene)bis(2,4-dialkylphenol) antioxidants under solvent free conditions and was reused several times without any appreciable loss of its catalytic activity even after eight consecutive cycles. In addition, the high yield of the products and non-toxicity of the catalysts are other worthwhile advantages of the present methods.
