Vanillin^1,2-propylene glycol acetal was synthesized from Vanillin and^1,2-propylene glycol using [(CH₂)₅NH₂]₄ SiMo₁₂O₄₀ as catalyst and benzene as water stripping agent. The effects of factors on yield of product, such as molar ratio of the reactant, catalyst dosage and reaction time were investigated. The exptl. results showed that [(CH₂)₅NH₂]₄ SiMo₁₂O₄₀ was catalyst with very good catalytic activity, and the catalyst was reused for 5 times. The preferential conditions were: based on 15.2g(0.1mol) of vanillin, the molar ratio of vanillin to^1,2-propylene glycol to n[(CH₂)₅NH₂]₄ SiMo₁₂O₄₀ 1 : 1.50 : 0.05; the amount of benzene as water stripping agent 20mL; and the reaction time 2.0 h.

Yu, Shuangjian published the artcileEffects of dynamic covalent bond multiplicity on the performance of vitrimeric elastomers, HPLC of Formula: 68527-74-2, the publication is Journal of Materials Chemistry A: Materials for Energy and Sustainability (2020), 8(39), 20503-20512, database is CAplus.

It is still a challenge to integrate multiple dynamic covalent bonds (DCBs) into one network, so the effects of DCB multiplicity on the performance of covalent adaptable networks (CANs) are still unclear. In this contribution, based on the versatility of vanillin chem., we realized the construction of CANs containing different DCB multiplicities, and thus the influences of DCB multiplicity on the vitrimeric performance of the networks are fairly investigated. It turns out that, with increasing DCB multiplicity, the relaxation time of the networks can be reduced significantly because the dynamic performance of the CANs with double or triple DCBs is determined by not only the activation energy but the synergistic effect of different DCBs. A plausible method was first proposed to quantify the synergistic effect of DCB multiplicity. We envisage that the disclosed findings will provide significant insight into the optimized design of CANs with tunable dynamic performance.
