Paragraph 0022-0028, (2017/12/04)

The invention provides a simple and convenient method for producing high-purity ortho-formate by using acrylonitrile byproduct hydrocyanic acid. The method comprises the following steps: firstly producing amine salt from the acrylonitrile byproduct hydrocyanic acid, fatty alcohol and hydrogen chloride, subsequently performing alcoholysis reaction on the presence of corresponding fatty alcohol so as to obtain an ortho-formate reaction liquid, adding a proper amount of an alkali substance in the generated ortho-formate reaction liquid, decomposing nitrogenous impurity compounds such as byproduct 1,3,5-s-triazine at certain temperature, wherein the decomposed product is nitrogen and solid formate with low boiling point, performing aftertreatment on the reaction liquid so as to obtain the high-purity ortho-formate through normal distillation. Therefore, the purpose of producing the high-purity ortho-formate with high yield is achieved.

Orthoester exchange: A tripodal tool for dynamic covalent and systems chemistry

Brachvogel, Ren-Chris,Von Delius, Max

, p. 1399 - 1403 (2015/02/05)

Reversible covalent reactions have become an important tool in supramolecular chemistry and materials science. Here we introduce the acid-catalyzed exchange of O,O,O-orthoesters to the toolbox of dynamic covalent chemistry. We demonstrate that orthoesters readily exchange with a wide range of alcohols under mild conditions and we disclose the first report of an orthoester metathesis reaction. We also show that dynamic orthoester systems give rise to pronounced metal template effects, which can best be understood by agonistic relationships in a three-dimensional network analysis. Due to the tripodal architecture of orthoesters, the exchange process described herein could find unique applications in dynamic polymers, porous materials and host-guest architectures.
