Petroleum ether Uses

  Naphtha (CAS NO.8030-30-6) is valuable for solvents because of its good dissolving power. The wide range of naphthas available, from the ordinary paraffinic straightrun to the highly aromatic types, and the varying degree of volatility possible offer products suitable for many uses. They are used in the rubber industry for dampening the play and tread stocks of automobile tires during manufacture to obtain better adhe-sion between the units of the tire. They are also consumed extensively in making rubber cements (adhesives) or are employed in the fabrication of rubberized cloth, hot-water bottles, bathing caps, gloves, overshoes, and toys. These cements are solutions of rubber and were formerly made with benzene, but petroleum naphtha is now preferred because of its less toxic character. They are used for extraction on, a fairly wide scale. They are applied in extracting residual oil from castor beans, soybeans, cottonseed, and wheat germ and in the recovery of grease from mixed garbage and refuse. They are also employed as solvents in the manufacture of printing inks, leather coatings, diluents for dyes, and degreasing of wool fibers, polishes, and waxes, as well as rust- and waterproofing compositions, mildew-proofing compositions, insecticides, and wood preservatives.

Petroleum ether Production

 Naphtha (CAS NO.8030-30-6) is divided into two main types, aliphatic and aromatic. Aliphatic naphtha is composed of paraffinic hydrocarbons and cycloparaffins (naphthenes), and may be obtained directly from crude petroleum by distillation. Aromatic naphtha contains aromatics, usually alkyl-substi-tuted benzene, and is very rarely, if at all, obtained from petroleum as straight-run materials; often reforming is necessary.
 In general, naphtha may be manufactured by any one of several methods, including:
 1. Fractionation of straight-run, cracked, and reforming distillates, or even fractionation of crude petroleum
 2. Solvent extraction
 3. Hydrogenation of cracked distillates
 4. Polymerization of unsaturated compounds (olefins)
 5. Alkylation processes
 In fact, the naphtha may be a combination of product streams from more than one of these processes.

Petroleum ether Safety Profile

A human poison via intravenous route. Experimental carcinogenic effects reported by skin contact. Human systemic effects by intravenous route: dyspnea, respiratory stimulation, and other unspecified respiratory effects. Mildly toxic by inhalation. Can cause unconsciousness, which may be followed by coma, stentorious breathing, and bluish tint to the skin. Recovery follows removal from exposure. In mild form, intoxication resembles drunkenness. On a chronic basis, no true poisoning; sometimes headache, lack of appetite, dizziness, sleeplessness, indigestion, and nausea. A common air contaminant. Flammable liquid when exposed to heat or flame; can react with oxidizing materials. Keep containers tightly closed. Slight explosion hazard. To fight fire, use foam, CO2, dry chemical. See also NAPHTHA, n-PENTANE, n-HEXANE, and HEPTANE.
