Oil seals are designed to fit around the rotating shaft of a machine or equipment. They create a barrier between the moving parts of the machinery and the external environment, ensuring that oil and other fluids do not leak out. This is vital for maintaining the efficiency and durability of the machinery, as leakage can lead to a loss of lubrication and increased wear and tear on the moving parts.

2. Chemicals and Plastics The compound serves as an intermediate in the production of various chemicals and plastics. It can be converted into propargyl derivatives, which find applications in the manufacturing of polymers and resins.

Vinegar is a staple in many households, renowned for its ability to preserve foods through pickling. The acetic acid found in vinegar creates an acidic environment that is inhospitable to bacteria. This method can be seen in various condiments and pickled vegetables, adding a tangy taste while ensuring safety.

Sodium bicarbonate (NaHCO₃) is a white crystalline powder that is mildly alkaline and has a slightly salty taste. It is an essential ingredient in baking; when mixed with an acid (like vinegar or lemon juice), it produces carbon dioxide gas, which helps dough to rise and achieve a light, airy texture. The chemical reaction can be represented as follows

In the complex world of food science, food additives play a critical role in enhancing the safety, taste, and shelf life of products. Among these additives, E504, also known as magnesium carbonates, is a lesser-known yet significant ingredient found in various food products. This article aims to unravel the purpose and safety of E504, shedding light on its uses and implications in our daily diets.

Glacial acetic acid, chemically known as ethanoic acid, is a colorless liquid with a pungent odor and is characterized by its high purity (at least 99% acetic acid). It is referred to as glacial because it solidifies at temperatures below 16.6 degrees Celsius (62 degrees Fahrenheit) into a crystalline structure resembling ice. This unique property, along with its distinct characteristics, makes glacial acetic acid an essential chemical in various industrial and laboratory applications.
