Abstract: The zeolite UTD-1 may be formed under hydrothermal synthesis conditions using a directing agent that does not include a metal atom therein. Methods for synthesizing the zeolite UTD-1 may comprise: combining at least a silicon atom source and a directing agent having a structure of in an aqueous medium; forming the zeolite in the aqueous medium under hydrothermal synthesis conditions, such that the zeolite has a framework silicate with a cationic portion of the directing agent occluded within pores or channels of the framework silicate; and isolating the zeolite from the aqueous medium. The zeolite has a powder x-ray diffraction pattern with at least the following 2θscattering angles: 6.0±0.12, 7.6±0.1, 14.66±0.15, 19.7±0.15, 21.27±0.15, 22.13±0.15, 22.61±0.15, and 24.42±0.10 for a borosilicate form zeolite, or 6.0±0.12, 7.6±0.15, 14.55±0.15, 19.64±0.15, 21.01±0.20, 21.90±0.20, 22.34±0.20, and 24.38 ±0.20 for an aluminosilicate form zeolite.

Abstract: A method can include heating an aqueous reaction mixture comprising a silicon source and a boron source and/or an aluminum source in the presence of a diquaternary structure directing agent to a temperature of at least 75° C. to produce a zeolite. A composition can include a borosilicate zeolite, an aluminosilicate zeolite, or an aluminoborosilicate zeolite having a framework symmetry of C2/m and a unit cell with measurements of a of 3.5 Å to 4.5 Å, b of 20.1 Å to 21.1 Å, c of 15.5 to 16.5 Å, and β of 97° to 98°.

Abstract: This disclosure relates to the preparation of diphenyl compounds, especially dimethylbiphenyl compounds, in which there is one methyl group on each ring, and their oxidized analogues. These compounds, and particularly alkylated biphenyl compounds and biphenylcarboxylic acids, alcohols and esters, are useful intermediates in the production of a variety of commercially valuable products, including polyesters and plasticizers for PVC and other polymer compositions.
