    摘要: In a process for oxidizing an alkylaromatic compound to the corresponding hydroperoxide, a feed comprising an alkylaromatic compound is contacted with an oxygen-containing gas in the presence of a catalyst comprising a cyclic imide. The contacting is conducted at a temperature of about 90° C. to about 150° C., with the cyclic imide being present in an amount between about 0.05 wt % and about 5 wt % of the alkylaromatic compound in the feed and the catalyst being substantially free of alkali metal compounds. The contacting oxidizes at least part of the alkylaromatic compound in said feed to the corresponding hydroperoxide.

    摘要: A method is described for preparing a molecular sieve-containing catalyst for use in a catalytic process conducted in a stirred tank reactor. The method comprises providing a mixture comprising a molecular sieve crystal and forming the mixture into catalyst particles having an average cross-sectional dimension of between about 0.01 mm and about 3.0 mm. The mixture may include a binder and the catalyst particles are then calcined to remove water therefrom and, after calcination and prior to loading the catalyst particles into a reactor for conducting the catalytic process, the catalyst particles are coated with a paraffin inert to the conditions employed in the catalytic process.

    摘要: C7-C12 secondary alcohol esters of cyclohexanecarboxylic acids are especially useful as plasticizers for PVC and other plasticizable polymers. In embodiments, these plasticizers are useful in plastisol formulations to help improved processability of flexiblePVC material. In other embodiments these same plasticizers can be used in blends with other plasticizers to improve processability. In preferred embodiments these same plasticizers can be used to prepare flexible PVC compounds with enhanced low temperature flexibility, low toxicity, and improved resistance to outdoor aging.

    摘要: A process for the oligomerization of propylene is disclosed wherein MCM-22 zeolite prepared as a distillation structure is used in a reaction distillation zone under conditions of temperature and pressure to concurrently react the propylene to produce oligomers thereof and separate the oligomer products from unreacted propylene by fractional distillation in a distillation column reactor. Compared to the prior art tubular or plug flow reactors, lower temperatures and pressures are used to produce higher conversions and selectivities to preferred isomeric forms.
