Pharmaceutical intermediates. Methylcyclohexane is an important organic solvent and extractant, which can be used as a solvent for rubber, paint, varnish (some paint solvents also use methylcyclohexane), and can be used as oil extractant. Methylcyclohexane can be used in organic synthesis as solvent and analytical reagent. In addition, methylcyclohexane can also be used as a standard for thermometer calibration. The correction solution is usually made of methylcyclohexane as the main component.

CAS: 90-72-2 2,4,6-Tris(dimethylaminomethyl)phenol Production Process and Method Brief introduction. 2,4,6-tris(dimethylaminomethyl)phenol, an organic chemical substance, molecular formula: C15H27N3O. Chinese name: 2,4,6-tris(dimethylaminomethyl)phenol Foreign name: 2,4,6-Tris(dimethylaminomethyl)phenol English alias: 2,4,6-tris[(dimethylamino)methyl]phenol Alias: Epoxy accelerator DMP-30; Tris(dimethylaminomethyl)phenol Appearance: transparent liquid Chemical formula: C15H27N3O Molecular weight: 271.4314 CAS No.: 90-72-2 EINECS number: 202-013-9 Boiling point: 320.50 ℃ Density: 1.054 g/cm³ Flash point: 116.63 ℃ Refractive index: 1.517 Epoxy resin curing accelerator DMP-30 is 2,4,6 tris(dimethylaminomethyl)phenol, which is a tertiary amine curing agent. It can be used as an epoxy resin curing agent at room temperature, and also as an efficient accelerator for acid anhydride, polyvinylamine and aliphatic polyamine curing agents. This product contains phenolic hydroxyl group in its molecular structure, so the activity is increased and it can be used for fast curing, mainly for thermosetting epoxy resin curing agent and adhesive, and it can be used as accelerator of acid anhydride curing agent and amide curing agent for casting and pressure layer products, the amount of this product as curing agent is generally about 3-13%, and the amount as accelerator is generally 0.1-3%. This product can be used as a catalyst in rubber anti-ozone agent and rigid polyurethane foam raw material combination polyether. Production process. 2000L reaction kettle, 200kg of phenol, 720kg of dimethylamine, 520kg of formaldehyde added dropwise below 50 degrees. kg, after drop addition, raise the temperature to 70 degrees, keep warm for 2 hours, lower the temperature to 50 degrees, add 100 kg of sodium chloride Sodium chloride, stir, let stand, stratify, and dehydrate the crude product under pressure. Method of preparation. After the reaction of phenol with dimethylamine and formaldehyde, the reaction products are stratified, dehydrated under vacuum and filtered to obtain the finished product. Theoretical unit consumption: (one ton of product) Phenol: 400 kg Dimethylamine (40% aqueous solution) 1440kg Formaldehyde (37% aqueous solution) 1040kg Produce waste water about 1.8 tons, mainly containing a small amount of formaldehyde Dosage: As accelerator dosage is about 1~5% As a curing agent dosage of about 10% Application areas.
