Introduction to Tolytriazole Sodium Salt Tolytriazole sodium salt, commonly known as sodium tolytriazole (CAS: 64665-57-2), is an organic chemical compound that belongs to the class of triazoles. Triazoles are five-membered heterocyclic compounds containing three nitrogen atoms, and tolytriazole is a derivative where the triazole ring is substituted by a tolyl group (methyl group on a

Abstract. Nitroguanidine (commonly abbreviated NGu or NQ; CAS 556-88-7) is a relatively low-sensitivity energetic solid widely used in propellants, pyrotechnics and insensitive munition formulations. From a chemical-engineering viewpoint it is interesting because its manufacture, handling and formulation require balancing energetic performance, particle engineering, quality control and rigorous safety/regulatory compliance. The purpose of this article is

1. Introduction to Molecular Sieves 1.1 What is a molecular sieve? A molecular sieve is a porous solid material whose pores (or “cages” / “channels”) have well-defined and extremely uniform diameters on the molecular scale (typically 3–10 Å). Because of this, the material can selectively adsorb or exclude molecules based on their kinetic diameter (size), shape,

Introduction to Photoinitiator 127 Photoinitiator 127, also known by trade names such as Omnirad 127 or Irgacure 127, is a difunctional α-hydroxyketone (AHK) photoinitiator widely used in ultraviolet (UV)-curable systems. This compound plays a vital role in initiating free-radical polymerization upon exposure to UV light, allowing for rapid curing of coatings, inks, adhesives, and related

1. Introduction of SIBX The mining industry faces a wide range of challenges, particularly in the extraction and processing of minerals. One of the critical stages in mineral processing is the flotation process, where the separation of valuable minerals from gangue (waste) materials occurs. In this process, the use of chemical reagents plays a pivotal

1. Introduction to Acrylic Acid Acrylic acid (IUPAC name: propenoic acid) is an unsaturated monocarboxylic acid with the molecular formula C₃H₄O₂. It is a clear, colorless liquid with a pungent odor and is primarily used as a precursor for acrylate esters and polyacrylic acid polymers. Its structural features—a vinyl group conjugated with a carboxylic acid—make
