WitrynaHydrocarbon resins are amorphous thermoplastic polymers produced by polymerization of unsaturated hydrocarbons. The feedstock are various by-products of naphtha crackers. 1 These resins have typically a low molecular weight ranging from about 400 to 5000 g/mol. The three main types are C5 aliphatic, C9 aromatic, and DCPD … Various qualifiers have been added to the term "naphtha" by different sources in an effort to make it more specific: One source distinguishes by boiling point: Light naphtha is the fraction boiling between 30 °C and 90 °C and consists of molecules with 5–6 carbon atoms. Heavy naphtha boils between 90 °C … Zobacz więcej Naphtha is a flammable liquid hydrocarbon mixture. Mixtures labelled naphtha have been produced from natural gas condensates, petroleum distillates, and the distillation of coal tar Zobacz więcej The word naphtha is from Latin and Ancient Greek (νάφθα), derived from Middle Persian naft ("wet", "naphtha"), the latter meaning of which was an assimilation from the Akkadian napṭu (see Semitic relatives such as Arabic نَفْط nafṭ ["petroleum"], Zobacz więcej • Coleman fuel • Fluid catalytic cracking • Greek fire • Hydrocarbon Zobacz więcej Heavy crude oil dilution Naphtha is used to dilute heavy crude oil to reduce its viscosity and enable/facilitate transport; undiluted heavy crude cannot normally be … Zobacz więcej The safety data sheets (SDSs) from various naphtha vendors indicate various hazards such as flammable mixture of hydrocarbons: flammability, carcinogenicity, skin and airway irritation, etc. Humans can be exposed to naphtha in the workplace by … Zobacz więcej

WitrynaPetroleum benzine is a hydrocarbon-based solvent mixture that is classified by its physical properties (e.g. boiling point, vapor pressure) rather than a specific chemical composition. This complicates distinction within the long list of petroleum distillate solvent mixtures: mineral spirits, naphtha, petroleum naptha, white gas, white spirits ...

WitrynaNaphthalene is the most abundant single component of coal tar. The composition of coal tar varies with coal type and processing, but typical coal tar is about 10% naphthalene by weight. In industrial practice, distillation of coal tar yields an oil containing about 50% naphthalene, along with twelve other aromatic compounds. chicken teriyaki recipe freezer meal
