THE ACTION OF MINERAL ACID ON DIETHYL BIS(HYDROXYMETHYL)MALONATE¹

Abstract

Iii a continuing study of methods for synthesizing a-(halomethyl)acrylic derivatives,3 the action of mineral acid on diethyl bis (hydroxymethyl)malonate has been examined. From the results obtained, it seems reasonable to conclude that when diethyl bis(hydroxymethyl)malonate is heated with concentrated mineral acid, a-(hydroxymethyl)acrylic acid is obtained as the first isolable product. If the mineral acid is a halogen acid, displacement of the allylic hy-HOCH2

Polyglycidyl nitrate (PGN)‐based energetic thermoplastic polyurethane elastomers with bonding functions

“…Diethyl Bis(hydroxymethyl)malonate (DBM) was made in our laboratory and obtained with a purity of 97.6% using isopropyl ether recrystallization. The OH equivalent of DBM is 9.09 mmol/g . RDX was provided by Baiyin Yinguang Chemical Material Factory.…”

Facile Synthesis and Polymerization of Ether Substituted Methacrylates

“…Monomers 7a-7e were synthesized to study the effect of incorporation of two bulky pendant groups per monomer molecule on polymer properties. Synthesis of these monomers from the reactive intermediate CMAC (6) was facile, involving reaction of 2.2 mo! of the required hydroxy-terminated species with I mo!…”

A novel method of preparing some new αα‐disubstituted vinyl monomers and their polymerizability. I. Synthesis of methyl α‐phenoxymethylacrylate and its polymerizability

“…Preparation of PP-dibromoisobutyric acid. 7 One mole of product from step 1 and 800 ml of 48% hydrobromic acid solution were combined and heated until ethylbromide began to distill.…”
