    摘要： The present invention provides a process for the preparation of p-toluic acid by liquid phase oxidation of p-xylene using oxygen or air as oxidant in the presence of p-toluic acid, water as solvent and cobalt salt or its combinations with salts of Ce, Mn as catalyst. Oxidation is carried out at 130-190° C. and pressure sufficient to keep water in liquid state. Oxidation step is followed by filteration to obtain p-toluic acid as major product. Unreacted p-xylene is recovered and recycled and the catalyst is recovered from aqueous phase and is recycled.

    摘要： Fatty acid alkyl esters suitable for use as biodiesel are produced by a single step esterification of free fatty acids and transesterification of triglycerides from vegetable oils or animal fats or combinations thereof with a lower alcohol (e.g. methanol) in presence of alkyl Tin oxide as catalyst. The ester thus produced is purified by distillation, treatment with an adsorbent, washing with water or combination thereof to give esters suitable for use as biodiesel.

    摘要： A method of providing a display (10) for a graphical user interface in which a user may define a selected region (20) of a subject image (3) is disclosed together with a computer program, a computer-readable storage medium (72) and apparatus for the same (71). The method comprising the steps of displaying the subject image (3); displaying at least one mask (12, 13, 14, 15) over the subject image wherein at least part of the or each mask extends to the periphery of the subject image (11); and defining the selected region (20) as those parts of the subject image not covered by a mask. The or each mask has a geometry which may vary in accordance with a user's input whereby the user selecting a first point within a mask and a second point displaced therefrom causes the geometry of that mask to vary in relation to the displacement (16, 17, 18, 19, 21) between the first and second points.
