Has anyone heard of 260# and 320# solvent oils?

Introduction to 260# solvent oil: It is produced using kerosene as raw material, through hydrogenation for refining and desulfurization/denitration, followed by dewaxing using molecular sieves. It features a high flash point, low freezing point, strong solvency, and is safe and reliable, making it suitable for replacing kerosene as a solvent. It is also widely used in industries such as mineral extraction and coal mining flotation agents, and can serve as a blending component for low-viscosity fuels.

I’ve never seen solvent oil with a 360# rating; could there be a mistake?

Based on the distillation temperature of 98% of the total volume or the dry point, it is classified into grades 70, 90, 120, 190, 200, and 260

According to **standard GB1922-88, solvent oils are classified based on their 98% distillation temperature or dry point. Common grades include: 70# floral solvent oil, 90# petroleum ether, 120# rubber solvent oil, 190# detergent oil, 200# paint solvent oil, and 260# special kerosene-type solvent. In addition, there is also 6# extraction solvent oil, aviation washing gasoline, and 310# colored ink solvent oil. Agricultural locust-killing solvent oils, etc. In fact, much more than this is available on the market; manufacturers can produce solvent oils in various specifications according to users’ needs. Solvent oil production involves two processes: cutting fractions and refining. There are generally three ways to extract fractions: directly from an atmospheric distillation column ； The corresponding light straight-run fractions are further cut into appropriate narrow fractions ； And fractionate the catalytic reforming raffinate oil. Various solvent oil fractions generally require refining. To improve color, enhance stability, remove corrosive substances, and reduce toxicity, etc. Common refining methods include alkali washing, clay refining, and hydrogenation refining. :lol

Hello, the 260# solvent oil produced by Maoming Zhengmao Petrochemical Co., Ltd. (also known as sulfonated kerosene) is a special type of kerosene-based solvent oil that is obtained through precise distillation, separation, and refining of hydrogenated raw materials. It has a wide range of applications, being used extensively in the extraction and processing of rare earth elements and non-ferrous metals (including cobalt, nickel, gold, copper, molybdenum, manganese, vanadium, etc.)； Used as a detergent for cleaning mechanical parts and precision metal products, such as aluminum foil and various aluminum alloy products, to enhance their brightness ； Used as a cooling cleaning agent in electric spark cutting, it helps to keep the workpiece surface smooth ； Carburizing metal workpieces through drip decomposition can improve the hardness and wear resistance of their surfaces ； Used as auxiliary agents in textile printing and dyeing, as fuel for miner’s lamps, as an extractant for fragrances, and in the formulation of cosmetics ； Fuel used for lighting and various burners, gas lamps, vaporizers, and kerosene stoves ； Solvent for the rubber and pharmaceutical industries, ink thinner, and feedstock for pyrolysis in the organic chemical industry ； Oils for use in processes such as the glass-ceramics industry, aluminum sheet rolling, and chemical heat treatment of metal workpieces’ surfaces ； To learn more about 260# solvent oil, visit http://www.gdzmsh.com/product/html/?87.html. As for 320#, we do not produce it nor have we come into contact with it.
