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
