Latest Patents

One of his latest patents is titled "Process for preparing ε-caprolactone." This invention provides a method for producing ε-caprolactone with a purity exceeding 99%. The process involves cyclizing 6-hydroxycaproic esters in the liquid phase at temperatures ranging from 150 to 400°C and pressures from 1 to 1020 hPa abs. It also includes the removal and condensation of volatile compounds during cyclization, followed by thermal treatment of the remaining bottom product to obtain ε-caprolactone through distillation.

Another significant patent by Andress is "Process for preparing polyalcohols from formaldehyde having a low formic acid content." This invention relates to the preparation of polymethylol compounds by condensing aldehydes with formaldehyde using tertiary amines as catalysts. The process is particularly innovative as it utilizes an aqueous formaldehyde solution with a formic acid content of less than 150 ppm, which effectively prevents the formation of by-products and increases the yield of the desired compounds.
