Urea plant using ammonium carbamate briquettes, Fixed Nitrogen Research Laboratory, ca. 1930 Carl Bosch, 1927. The Bosch–Meiser process is an industrial process, which was patented in 1922 [1] and named after its discoverers, the German chemists Carl Bosch and Wilhelm Meiser [2] for the large-scale manufacturing of urea, a valuable nitrogenous chemical.
Urea-formaldehyde (UF), also known as urea-methanal, so named for its common synthesis pathway and overall structure, [1] is a nontransparent thermosetting resin or polymer. It is produced from urea and formaldehyde. These resins are used in adhesives, plywood, particle board, medium-density fibreboard (MDF), and molded objects.
The basic reaction of urea and formaldehyde to create a urea-formaldehyde resin, followed by the condensation [12] Urea-formaldehyde resins (UF) are a class of impregnation resins for wood modification made by reacting urea with formaldehyde. This resin can be polymerized after impregnation into the wood substrate by oven-curing.

After a summer full of grilled zucchini and yellow squash, now is the perfect time to switch things up and cook some winter squash. So what exactly sets summer and winter squash varieties apart?
Methylol urea is the organic compound with the formula H 2 NC(O)NHCH 2 OH. It is a white, water-soluble solid that decomposes near 110 °C. Methylolurea is the product of the condensation reaction of formaldehyde and urea. As such it is an intermediate in the formation of urea-formaldehyde resins [1] as well as fertilizer compositions such as ...
