Abstract:
A support frame for a drawer-type dishwasher includes a top section and opposing side sections formed from a plurality of support members which define an open lattice work and establish a cavity for a slidable dishwasher drawer. The support frame also includes first and second rail supports that are provided on respective ones of the opposing side sections. The first and second rail supports are designed to support corresponding first and second extensible rails which, in turn, support the wash tub for movement relative to the frame. In addition, the support frame includes lid support elements for a mechanism that provides shifting of a lid member relative to the wash tub.
Abstract:
Provided herein is a process for producing alkylene carbonates of ultra-high purity. According to the present invention, certain stages of traditional distillation of alkylene carbonate distillation are replaced by carbon treatment. Alkylene carbonates produced according to the invention have a color of less than 25 (Pt-Co), and are suitable for uses requiring ultra-pure alkylene carbonates.
Abstract:
A method for preparing tertiary butyl alcohol wherein a feedstock comprising a solvent solution of tertiary butyl hydroperoxide in tertiary butyl alcohol or a mixture of tertiary butyl alcohol with isobutane is charged to a hydroperoxide decomposition reaction zone containing a catalytically effective amount of a hydroperoxide decomposition catalyst consisting essentially of alumina having gold-promoted palladium deposited thereon and is brought into contact with the catalyst in liquid phase with agitation under hydroperoxide decomposition reaction conditions to convert the tertiary butyl hydroperoxide to decomposition products, principally tertiary butyl alcohol.
Abstract:
In the non-catalytic liquid phase oxidation of isobutane, it has been found that the reaction is initiated with 0.05 wt % to 0.08 wt % ditertiary butyl peroxide.
Abstract:
Synthetic lubricant base stocks having improved properties are disclosed. The base stocks may be obtained by a two-step process, comprising the steps of (1) co-reacting vinylcyclohexene and long-chain linear olefin with a free-radical initiator; and (2) further reacting the mixture resulting from step (1) in the presence of an acidic montmorillonite clay.
Abstract:
A method for preparing tertiary butyl alcohol wherein a feedstock comprising a solvent solution of tertiary butyl hydroperoxide in tertiary butyl alcohol or a mixture of tertiary butyl alcohol with isobutane is charged to a hydroperoxide decomposition reaction zone containing a catalytically effective amount of a hydroperoxide decomposition catalyst consisting essentially of lead oxide supported on alumina and is brought into contact with the catalyst in liquid phase with agitation under hydroperoxide decomposition reaction conditions to convert the tertiary butyl hydroperoxide to decomposition products, principally tertiary butyl alcohol.
Abstract:
A non-diluent oil process for producing a fluid sulfurized/neutralized phenate comprising:a) oligomerizing a (C.sub.6 -C.sub.20) olefin;b) alkylating the oligomerized olefin to produce a oligomerized (C.sub.6 -C.sub.20) alkyl phenol;c) neutralizing and sulfurizing the oligomerized (C.sub.6 -C.sub.20) alkyl phenol to produce a fluid neutralized/sulfurized phenate product; andd) recovering said fluid phenate product.
Abstract:
Tertiary butyl alcohol contaminated with residual amounts of peroxide contaminants such as tertiary butyl hydroperoxide, ditertiary butyl peroxide, allyl tertiary butyl peroxide, etc., (which may be prepared, for example, by catalytically reacting propylene with tertiary butyl hydroperoxide to form propylene oxide and tertiary butyl alcohol) can be effectively catalytically treated under mild conversion conditions including a temperature of about 100.degree. to about 300.degree. C. with a catalyst comprising ferrous oxide to substantially completely decompose the peroxide contaminants to thereby provide a treated tertiary butyl alcohol product substantially free from contaminating quantities of such peroxides.
Abstract:
Motor-fuel tertiary butyl alcohol contaminated with residual amounts of tertiary butyl hydroperoxide, ditertiary butyl peroxide and allyl tertiary butyl peroxide (which is prepared, for example, by reacting propylene with tertiary butyl hydroperoxide to form propylene oxide and a motor fuel grade tertiary butyl alcohol reaction product) can be effectively catalytically treated under mild conversion conditions including a temperature of about 160.degree. to 200.degree. C. with a catalyst consisting essentially of vitrified silica to substantially completely decompose the peroxide contaminants to thereby provide a treated tertiary butyl alcohol product substantially free from contaminating quantities of such peroxides.
Abstract:
A method for preparing tertiary butyl alcohol wherein a solution of a tertiary butyl hydroperoxide feedstock comprising a solution of tertiary butyl hydroperoxide in tertiary butyl alcohol is charged to a hydroperoxide decomposition reaction zone containing a catalytically effective amount of a hydroperoxide decomposition catalyst consisting essentially of a mixture of a soluble cycloalkenyl iron compound with a soluble ruthenium compound, and is brought into contact with the catalyst in liquid phase with agitation under hydroperoxide decomposition reaction conditions to convert the tertiary butyl hydroperoxide to decomposition products, principally tertiary butyl alcohol.
