    摘要： A process for preparing (meth)acrylates of C17-alcohol mixtures by reacting (meth)acrylic acid with a C17-alcohol mixture in the presence of at least one acidic catalyst and of at least one polymerization inhibitor and in the presence of a solvent which, with water, forms an azeotrope in which the esterification is performed in a reactor with a circulation evaporator, the azeotrope is distilled off and condensed, and the condensate splits into an aqueous phase and an organic phase, wherein the C17-alcohol mixture has a mean degree of branching (iso index) of 2.8 to 3.7.

    摘要： The disclosure provides methods and systems for the production of biodiesel from biological feedstocks such as vegetable oils or animal fats. In particular, the disclosure is directed to the product of biodiesel from seeds such as non-edible oil seeds. Methods for maximizing oil recovery from the feedstocks are provided, as well as methods to convert free fatty acids in the feedstocks into glycerides amenable to transesterification. Thus the methods and systems provide for efficient biodiesel production.

    摘要： A process of fabricating weather resistant signage by screen printing indicia on a UV-treated impregnated polyester protective film using a Cellosolve acetate-based ink. The resulting sign is extremely resistant to solar UV, thus preserving the indicia brightness and clarity for a very long period of time even under the most extreme conditions. The screen printing process of the preferred embodiment comprises the steps of first preparing a film image, then preparing a fabric mesh ranging from 125 to 230 mesh for black and white images and ranging from 355 to 425 mesh for halftone color images. The fabric mesh is attached to a stencil and the film image is attached to the stencil. The combination is placed into a vacuum frame for exposure to high intensity light, after which the stencil is washed with pressurized water, dried by fan, taped and touched up for pinholes or other blemishes. The ink used in the preferred embodiment comprises a clear base having Cellosolve acetate, SC-150 aromatic solvent, VITEL PE-200, VITEL PE-222 and VITEL PE-307 solvent-based coating resins, as well as thinner and resin and other ingredients. The preferred embodiment of the invention uses a unique substrate for the sign material. Generally, the substrate comprises a UV treated, impregnated polyester protective film.

    摘要： For the oligomerization of a fatty ester or fatty acid containing conjugated double bonds, the reaction uses a catalyst consisting of an activated earth, e.g., montmorillonite, at a temperature of from 100.degree.-180.degree. C., preferably from 130.degree.-160.degree. C. The process can be carried out continuously or in a batch process on a fixed bed and is particularly applicable to conjugated methyl esters obtained by conjugating and transesterifying sunflower seed oil. The oligomerized products obtained are particularly useful as lubricants or polycondensation reactants.
