Cheng, Yunlei; Cao, Youming published the artcile< Synthesis of imine carboxylic acid chelating resin>, COA of Formula: C19H34O2, the main research area is bromostyrene divinylbenzene copolymer diethyl iminodiacetate reaction chelating resin synthesis.
An imine carboxylic acid chelating resin was synthesized via suspension polymerization with 1, 2-divinyl benzene (o-DVB) and iminodiacetic acid di-Et ester as feedstock, polyethylene glycol as emulsifier, NaCl water solution as dispersed phase, and toluene as oil phase solvent. The functional group and morphol. of the product were characterized, and the impact of bromide time, initiator, mole ratio of feedstock on yield of brominated polystyrene were observed as well. The yield of brominated polystyrene increases and then decreases with the increasing of bromide time, and the optimal bromide time is 45 min; it also surges then drops slightly with the initiator increasing and reaches the peak of 72% when the initiator is 0.18 g; the yield of the product follows the increasing of the mole ratio of o-DVB and brominated DVB, while the destiny of functional group is decreased. There the more the initiator are, the smaller the particle of brominated polystyrene becomes, and the greater granulation rate achieves.
Hecheng Shuzhi Ji Suliao published new progress about Bromination. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, COA of Formula: C19H34O2.
