  What Is Hydrogen Peroxide Good For?   Found in a brown bottle, hydrogen peroxide is an antiseptic liquid that in the past was typically used to treat cuts or other skin wounds, and kill germs. However, peroxide is often used in non-medical situations, including for cleaning, disinfecting and stain removal.    What is Hydrogen Peroxide?   Hydrogen peroxide (H₂O₂)  is essentially water (H₂O) with an extra oxygen molecule. This additional oxygen molecule gives hydrogen peroxide its powerful oxidizing properties, which enable it to kill germs and bleach porous surfaces like fabrics.   For everyday household use, medical-grade hydrogen peroxide—which is 3% peroxide and 97% water—is strong enough and widely available.   A more concentrated version, known as food-grade hydrogen peroxide, can have strengths up to 35%. Despite its name, "food-grade" peroxide is not intended for general cleaning or disinfecting and can be hazardous if inhaled or if it com...

  Sodium percarbonate is produced by the reaction of sodium carbonate with hydrogen peroxide, which can be done via dry, spray granulation and crystallization processes. In the dry process aqueous hydrogen peroxide solution is sprayed on solid sodium carbonate; a solid-liquid reaction yields sodium percarbonate.   What Is Sodium Percarbonate? Sodium percarbonate, also referred to as sodium carbonate peroxide, is a solid chemical compound made by combining sodium carbonate and hydrogen peroxide. Essentially, it is a form of solid hydrogen peroxide. The combination of these two chemicals forms a highly effective cleaning agent, often included in eco-friendly household products.   Production Process of Sodium Percarbonate 1. Raw Materials: Hydrogen Peroxide and Sodium Carbonate The two key ingredients in the production of sodium percarbonate are  hydrogen peroxide (H₂O₂)  and sodium carbonate (Na₂CO₃). These chemicals undergo a reaction that results in the formatio...

  Methyl methacrylate (MMA)  is a widely used organic compound, primarily known for its role in the production of polymethyl methacrylate (PMMA) and various acrylic resins. The process of manufacturing MMA involves various raw materials, and different production methods are applied based on availability and economic factors. In this article, we’ll dive into the essential raw materials used in MMA production, explore the methods involved, and how these materials come together to create a compound critical to modern manufacturing.   Understanding Methyl Methacrylate (MMA) MMA is a liquid organic compound that forms the building blocks of numerous plastic products, especially acrylic materials. These plastics are used in a wide variety of industries, including automotive, construction, and healthcare. Due to its transparency, strength, and weather resistance, MMA has become indispensable in today’s manufacturing landscape.   Common Uses of Methyl Methacrylate Before div...

  Mono-ethylene glycol (MEG)   is an important industrial chemical, primarily used as a precursor for polyester fibers, antifreeze, and as a component in other chemical applications. Given its wide usage, the efficient and environmentally friendly production of MEG is a topic of significant interest. Among the various methods for MEG production, the synthesis from syngas (a mixture of carbon monoxide and hydrogen) via CO coupling reactions has garnered attention for its potential to provide a green and efficient route.   The Syngas Route to MEG Production The synthesis of  mono-ethylene glycol  via syngas proceeds in two key steps. These include: 1. Carbonylation of Alkyl Nitrile – This is a self-closing, green step where alkyl nitriles undergo carbonylation to produce dialkyl oxalate. 2. Hydrogenation of Dialkyl Oxalate – In this step, the dialkyl oxalate is hydrogenated to produce mono-ethylene glycol.   This method stands out for its environmental friend...

 In today's world, sustainability is at the forefront of innovation, and one of the biggest challenges we face is how to reduce carbon dioxide (CO2) emissions. While CO2 is primarily known as a greenhouse gas contributing to global warming, recent advancements show that it can also serve a more constructive purpose—making plastics. Yes, you read that right! CO2, which was once just seen as a pollutant, is now being explored as a raw material for manufacturing sustainable plastics. But how is this possible, and what does it mean for the future of the plastics industry? Let’s dive into the fascinating world of CO2-based plastics.   What Are CO2-Based Plastics?   CO2-based plastics  refer to materials that use carbon dioxide as one of the core ingredients in the polymer-making process. These types of plastics are often referred to as “green plastics” due to their lower environmental impact compared to traditional petroleum-based plastics.   How Is CO2 Used in Plast...

 An air separation unit (ASU) uses the conventional multi-column cryogenic distillation technique to produce O2 from compressed air at high purity and recovery rate. ASU's energy consumption is related to recovery since it is linked to the air flow required by thermal power.   An  Air Separation Unit (ASU)  is an industrial process that separates atmospheric air into its primary components—namely nitrogen, oxygen, and sometimes argon and other rare inert gases. The process is essential for producing high-purity gases used in various industries, including healthcare, manufacturing, and chemical production. Here's a breakdown of how an ASU works:   1. Atmospheric Air Intake   The  air separation unit process  begins by drawing in atmospheric air. This air contains approximately 78% nitrogen, 21% oxygen, and 1% argon, along with trace amounts of other gases. The air is typically filtered to remove dust, moisture, and other impurities.   2. Compr...
