For example, benzene can be converted into phenol with a yield of at least 30-40%, and a selectivity on the basis of benzene of at least 95-97%. The selectivity for this reaction based on N2O is at least 90-95%. Therefore, no substantial N2O decomposition or consumption for complete benzene oxidation to CO+CO2 or other side products occurs. Similar results are obtained with benzene derivatives (e.g., fluorobenzene, difluorobenzene, phenol), although the selectivity is somewhat lower in the case of derivatives (e.g., about 80-85% in the case of fluorosubstituted benzenes). A preferred catalyst for this process is a composition containing a high-silica pentasil-type zeolite (e.g, an HZSM-5 type zeolite) which contains no purposefully introduced additives such as transition or noble metals.

  • Patent number: 6162931
    Abstract: The family of dyes of the invention are fluoresceins and rhodols that are directly substituted on one or more aromatic carbons by fluorine. These fluorine-substituted fluorescent dyes possess greater photostability and have lower sensitivity to pH changes in the physiological range of 6-8 than do non-fluorinated dyes, exhibit less quenching when conjugated to a substance, and possess additional advantages. The dyes of the invention are useful as detectable tracers and for preparing conjugates of organic and inorganic substances.

  • Patent number: 6156811
    Abstract: Molded polyurethane articles are made by reacting polyisocyanates with polyol compositions obtained by chemical decomposition of polyurethane and/or polyurea waste in a mold. The polyol compositions employed in this invention have an OH value of from about 100 to about 500 mg KOH/g, a water content of from 0 to about 5 wt. % and a viscosity at 20.degree. C. of more than 2,000 mPa.s. These molded polyurethane articles preferably have a sandwich structure in which the core is a polyurethane and there is at least one outer layer made from an optionally fiber-reinforced plastic material. These molded polyurethane articles are useful in the motor vehicle, furniture, machine and equipment manufacturing industries.

  • Patent number: 6080894
    Abstract: The propylene oxide and styrene co-production process generates a heavy residue byproduct containing metals, mainly sodium, which previously was adequate for use only as low quality fuel. According to the invention, the heavy residue is dehydrated in the presence of a strong inorganic acid at temperatures of 150-250.degree. C. and pressures below the atmospheric pressure to yield styrene and recover 2-phenylethanol, a compound used in the perfume industry, and a heavy residue substantially free of metals that may be used as fuel.

  • Patent number: 6049013
    Abstract: A method for producing an alcohol including the steps of continuously supplying and flowing starting materials of an alcohol in a reducing reactor; and carrying out catalytic reduction reaction of the starting materials with hydrogen gas in the presence of a hydrogenation catalyst. In this method, the catalytic reduction reaction of the starting materials is carried out under temperature conditions of not less than a dew point of the resulting alcohol, and the starting materials of an alcohol are brought in contact with hydrogen gas in the presence of a hydrogenation catalyst, in which at least one substance selected from the group consisting of starting materials of an alcohol, alcohols, wax esters, and hydrocarbons is present in a liquid form on a surface or within pores of the hydrogenation catalyst.
