Safety of 4-Butylbenzene-1,2-diolOn November 8, 2016 ,《Sulfo-and carboxybetaine-containing polyampholytes based on poly(2-vinyl pyridine)s: Synthesis and solution behavior》 appeared in Polymer. The author of the article were Billing, Mark; Elter, Johanna K.; Schacher, Felix H.. The article conveys some information:
We present the synthesis and characterization of zwitterionic homopolymers and copolymers based on poly(2-vinyl pyridine) (P2VP). Different molar masses as well as copolymer compositions of poly(styrene-co-2-vinyl pyridine) (P(2VP-co-S)) were synthesized using RAFT (reversible addition fragmentation chain transfer) polymerization, followed by quaternization of the nitrogen atom by either 1,3-propanesultone (P2VPS, P(2VPS-co-S)) or ethyl-2-bromoacetate, followed by ester hydrolysis (P2VPC, P(2VPC-co-S)). The resulting materials were characterized using SEC, 1H and 13C NMR spectroscopy, elemental anal., and zeta potential measurements. Degrees of functionalization ranging from 33 to 76% could be determined and both P2VPC and P2VPS exhibited good solubility over the entire pH-range. Upon incorporation of increasing amounts of styrene, aqueous solubility decreased and also UCST behavior could be observed in case of P(2VP56,S-co-S44). In the experiment, the researchers used many compounds, for example, 4-Butylbenzene-1,2-diol(cas: 2525-05-5Safety of 4-Butylbenzene-1,2-diol)
4-Butylbenzene-1,2-diol(cas: 2525-05-5) belongs to organoboron compounds. Organoboron compounds are versatile intermediates and as such are some of the most important classes of reagents in modern organic chemistry.Safety of 4-Butylbenzene-1,2-diol Organoboron compounds are less toxic than organostannane reagents, and unlike alkynylzinc and magnesium, many organoboron compounds possess remarkable oxidative and thermal stabilities.
