  Formic acid, a simple carboxylic acid with the chemical formula HCOOH, is extensively used across numerous industries due to its versatile properties. This article explores the various production technologies employed to manufacture formic acid, detailing the processes, advantages, and applications.   The Basics of Formic Acid Formic acid  is naturally found in some ants and plants, and it serves as an essential industrial chemical. Its applications range from leather tanning and textile dyeing to agriculture and food preservation. The following sections highlight the primary methods used for its industrial production.   Methanol Carbonylation One of the most prevalent methods for producing formic acid involves the carbonylation of methanol. This process entails the reaction of methanol with carbon monoxide in the presence of a catalyst, usually a metal complex like rhodium or cobalt.   Process Steps: 1. Methanol Preparation: Methanol is purified and dried to ...

  Methyl methacrylate (MMA) ​ is an unsaturated ester monomer widely employed in polymer production. Its main application lies in the synthesis of Poly(methyl methacrylate) (PMMA) homopolymers. PMMA is a clear and hard synthetic plastic.   In addition, MMA is the basis for many acrylate polymers and is an essential copolymer monomer in the formulation of paints, coatings and adhesive resins. Applications include safety glass, exterior paints, vinyl impact modifiers, adhesives, lighting displays, etc.   MMA is also utilized in copolymerization with styrene and butadiene to produce additives for polyvinyl chloride (PVC), enhancing its properties. Additionally, MMA undergoes ester-exchange reactions to create specialty methacrylate monomers.   PMMA finds industrial application in the manufacture of cast and extruded acrylic sheets. These cast PMMA sheets exhibit excellent optical clarity, high transparency, and UV stability. Moreover, PMMA is biocompatible, ma...

  What is MMA monomer? Methyl methacrylate (MMA) is a monomer that’s also known as methacrylic acid, methyl ester.   A key building block for acrylic-based polymers, MMA has applications that include safety glazing, exterior paints, vinyl impact modifiers, adhesives, illuminated light displays, and more. There are several synthetic ways to make the MMA chemical as the one most widely used is the three-step process of adding acetone to hydrogen cyanide (HCN) and moves to acetone cyanohydrin.   History of Methyl Methacrylate   The history of the formulation of methyl methacrylate monomer began during a time when acrylic acids were first being synthesized in the early 1800s. German chemists took roughly 85 years to develop acrylic acid in 1843. Then it took another 22 years for them to make methacrylic acid, and then from that step methanol was added to form the chemical reaction of methyl methacrylate, which would become known as acrylic polymer.   Yet still ...

  What Is Acrylic (PMMA)?   Acrylic, also known as  Polymethyl Methacrylate (PMMA) , is a transparent and rigid plastic commonly used as a substitute for glass in products such as shatterproof windows, illuminated signs, skylights, and aircraft canopies. PMMA is an important member of the acrylic family of resins, created through the polymerization of methyl methacrylate.   PMMA is also referred to by various trade names and brands, including Crylux, Plexiglas, Acrylite, Perclax, Astariglas, Lucite, and Perspex. It is often used in sheet form as a lightweight and shatter-resistant alternative to glass. Additionally, PMMA can be used as a casting resin and in inks and coatings. PMMA belongs to a group of materials known as engineering plastics.   How Is Acrylic Made?   Polymethyl methacrylate is made through polymerization, as it is one of the synthetic polymers. First, methyl methacrylate is put in a mold with a catalyst added to speed up the process. Becau...

  Measuring Hydrogen Peroxide in the Paper and Pulp Industry   Hydrogen peroxide is one of the most common bleaching agents. It is used as the primary bleaching agent in the textile industry, and is also used in pulp, paper, and many home laundry applications. Alkaline hydrogen peroxide is used as a bleaching agent for the mechanical pulp. The amount of base such as sodium hydroxide is less than that which is used in bleaching chemical pulps and the temperatures are lower.   How Can Hydrogen Peroxide Be Used as a Bleaching Agent?   In the textile industry, it is commonly used for bleaching cotton fabric. The addition of magnesium sulfate in the bleaching formula helps stabilize the bleaching system for cationized cotton, improving whiteness index and fabric strength. In the pulp and fiber industry, hydrogen peroxide is used to eliminate lignin content and achieve high color brightness. The concentration of hydrogen peroxide used affects the degree of whiteness and fa...
