Have experts carried out the hydrogenation of aniline? Is there a better catalytic system that can increase the production of diphenylamine as a byproduct? A generous reward will surely be given! Contact: ff6605js94@163.com
What are the differences and connections between fine chemicals and polymers? ? Please, the original poster, answer
1 Hydrogenation of aniline to cyclohexylamine ； 2 Dianiline is prepared by the condensation of aniline under heating and in the presence of an oxide catalyst, with ammonia being released as a byproduct.
1 Fine chemicals: pharmaceuticals, pesticides, synthetic dyes, organic pigments, coatings, fragrances and flavorings, cosmetics and personal care products, soaps and synthetic detergents, surfactants, printing inks and their additives, adhesives, photosensitive materials, magnetic materials, catalysts, reagents, water treatment agents and polymer flocculants, papermaking additives, leather processing additives, additives for synthetic materials, textile dyes and finishing agents, food additives, feed additives, veterinary drugs, chemicals for oil fields, petroleum additives and refining aids, cement additives, mineral flotation agents, chemicals for casting, metal surface treatment agents, synthetic lubricants and lubricant additives, chemicals for use in automobiles, aromatic deodorants, industrial antimicrobial and antifungal agents, electronic chemicals and materials, functional polymer materials, biochemical products, and more – covering over 40 different industries and categories. 2 Polymer chemistry is an emerging industry for synthetic materials, encompassing sectors such as the plastics industry, synthetic rubber industry, rubber industry, chemical fiber industry, as well as the coatings industry and adhesives industry. 3 Fine polymer chemistry is a part of fine chemical industry.
I’ve learned it, thank you very much. It’s a pity it costs money; I’ll give it to you next time: lol
Original poster, I was wondering if there are any suitable thickeners available to thicken organic solvents such as dichloromethane, toluene, and propylene
Why add thickeners? Unnecessary additives in chemical reactions can affect product quality.
The recipe requires this to be done; it’s not something I want to do, but it’s necessary! Without explaining why, just ask if it’s possible
Xylene thickener is a high-grade, non-toxic, and environmentally friendly product with excellent thickening, gelling, bonding, and suspending properties. It can be used as a thickener and suspending agent, and is soluble in organic solvents such as toluene and xylene. It is mainly used in the chemical industry sectors such as pesticides, high-quality paints, inks, and coatings.
I wonder if it’s available there? Could you provide some samples for testing?
