And the article was included in Gaoxiao Huaxue Gongcheng Xuebao in 2013.Application In Synthesis of 2-Butyl-2-ethylpropane-1,3-diol The following contents are mentioned in the article:
The third generation hyperbranched polyesters (HBPs) were synthesized by the pseudo-one step method with 2, 2-bis(hydroxyl-methyl) propionic acid as AB2 monomer, p-toluene sulfonic acid as catalyst, in which 2-butyl-2-ethyl-1, 3-propanediol (BEPD, HBP-1), 1, 4-butanediol (BDO, HBP-2), and neopentyl glycol (NPG, HBP-3) were used as the core monomers, resp. The structures and mol. weights of HBPs were characterized with FT-IR, NMR and GPC as well as their intrinsic viscosities were also given. The film properties of HBPs cured by the toluene diisocyanate adduct were tested. The thermal stability of cured HBPs films were also examined by thermogravimetric anal. (TGA). It was found that HBPs are successfully synthesized and HBP-1 displays the highest branching degree up to 0.55. The GPC measured mol. weights of HBPs approach to the theor. values, and HBP-1 exhibits the lowest polydispersity index up to 1.68. HBPs are soluble in strong polar solvents and insoluble in non-polar solvents and HBP-1 displays better solubility and lower intrinsic viscosity up to 4.24 mL·g-1. The cured HBPs films exhibit good thermal stability, adhesion, flexibility, and high hardness. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Application In Synthesis of 2-Butyl-2-ethylpropane-1,3-diol).
2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Application In Synthesis of 2-Butyl-2-ethylpropane-1,3-diol
