Description
Solvent Naphtha is an aromatic hydrocarbon solvent made mainly from aromatic compounds.
Naphtha can be divided into light and heavy types, are aromatic hydrocarbon solvents primarily made from C9, C10 and C10-C13 aromatic compounds.
Heavy solvent naphtha is harmful to health, and possibly carcinogenic, and are to be labelled H351 “Suspected of causing cancer”.

Less dense than water and insoluble in water.
Vapors heavier than air.
Description
Naphtha is a broad term used for a group of volatile, flammable liquid hydrocarbon mixtures obtained primarily from petroleum refining and, in some cases, from natural gas processing or coal-derived sources.
Its exact composition varies depending on the source and refining process, but Naphtha generally contains hydrocarbons in the approximate C5–C12 range, including paraffins, cycloparaffins (naphthenes), and aromatic hydrocarbons.
Naphtha can range from light, highly volatile fractions to heavy aromatic fractions with higher boiling points.
Naphtha is typically a colorless to pale yellow liquid with a characteristic petroleum-like odor and very low water solubility.
Naphtha is an important industrial feedstock and solvent.
Its properties, such as boiling range, aromatic content, volatility, density, and solvent power, depend strongly on its specific grade.
Heavy aromatic solvent naphtha, for example, contains a relatively high proportion of aromatic hydrocarbons and is commonly used where strong solvency and controlled evaporation are required.
Naphtha is a clear, highly flammable liquid made up of a mix of hydrocarbon molecules.
Naphtha is a middle-range fraction separated during the refining of crude oil or natural gas, containing molecules with 5 to 12 carbon atoms.
Properties
Solvent naphtha, light aromatic (CAS No. 64742-95-6) is a mixture of light aromatic hydrocarbons from refined petroleum distillates, with an aromatic content of 98% or greater.
Naphtha is composed primarily of C9-10 dialkyl and trialkylbenzenes.
Naphtha contains approximately 46% trimethylbenzenes, 36% ethylmethylbenzenes, 0 to 5% xylene, 0 to 5% cumene, and 1.5% ethylbenzene; the exact composition and concentrations vary.
Solvent Naphtha 150 is a colourless non-viscous liquid with a strong aromatic odour.
Naphtha is not soluble in water, but in aromatic solvents.
Uses
Petroleum Refining: Naphtha is used as an intermediate stream in petroleum refineries and can be further processed into fuels, solvents, and petrochemical feedstocks.
Petrochemical Feedstock: Light naphtha is an important feedstock for steam cracking and can be converted into ethylene, propylene, and other basic petrochemicals.
Gasoline Production: Naphtha fractions can be processed through catalytic reforming, isomerization, and other refinery processes to produce high-octane gasoline components.
Solvent: Naphtha is widely used as an industrial solvent for dissolving oils, resins, greases, waxes, and other organic materials.
Paints and Coatings: Aromatic naphtha grades are used as solvents in paints, coatings, varnishes, lacquers, and related formulations.
Adhesives and Sealants: Selected naphtha fractions are used as solvents and processing aids in adhesive and sealant formulations.
Rubber Industry: Naphtha can be used as a solvent and processing medium in the manufacture and formulation of rubber products.
Printing Inks: Certain grades are used as hydrocarbon solvents in printing ink formulations.
Agricultural Chemicals: Naphtha-based solvent systems can be used as carriers or formulation solvents for pesticides, herbicides, and other agricultural chemical products.
Metal Cleaning and Degreasing: Suitable naphtha fractions are used for removing oils, grease, waxes, and other hydrocarbon-based contaminants from metal surfaces.
Chemical Manufacturing: Naphtha serves as a feedstock or process solvent in the manufacture of various organic chemicals and specialty products.
Applications
Naphtha is applied extensively in petroleum refining, petrochemical production, solvent manufacturing, paints and coatings, adhesives, rubber processing, printing inks, industrial cleaning, and agricultural chemical formulations.
Heavy aromatic solvent naphtha is particularly useful in applications requiring high solvency, relatively low volatility compared with lighter hydrocarbon solvents, and compatibility with resins and other organic materials.
Definition
solvent naphtha is a flammable liquid distillate containing principally xylenes and higher aromatic hydrocarbons and usually boiling higher than ligroin, obtained especially from coal-tar light oils or coke-over-gas light oils or from petroleum cracking, and used chiefly as a solvent and as a raw material for coumarone-indene resins.
Uses
Solvent naphtha is used in the agricultural, chemical, textile processing and coatings industries.
Main Uses
Gasoline Production: Reformed in refineries to make high-octane blending components for fuel.
Plastics and Chemicals: Used in steam crackers to make ethylene and propylene for plastics.
Solvents: Acts as a degreaser, paint thinner (V.M.&P. naphtha), and ingredient in soaps or cleaning agents.
Flammability and Explosibility
