Vanillic acid (VA), an abundant renewable biomaterial derived from lignin, has been employed as a new building skeleton to formulate esters. These esters with different alkyl chains (VA4-Cn) were synthesized, characterized, and used plasticizers for phthalate-free flexible poly(vinyl chloride) (PVC). Miscibility analysis reveals that VA4-Cn exhibits good miscibility PVC the length of is key factor improving its miscibility. The blends vanillic display flexibility stretchability comparable or...
A series of tartaric acid (TA) esters with different side chain lengths [dibutyl TA (DBTAE)-Cn], as plasticizers for poly(vinyl chloride) (PVC), is herein reported. Their structures have been fully characterized using proton nuclear magnetic resonance and Fourier-transform infrared spectroscopy. compatibility plasticizing effect soft PVC were evaluated thermogravimetric analysis, dynamic mechanical tensile testing, migration testing. The results showed that all these exhibit good...
Biotreatment of acidic rare earth mining wastewater via acidophilic living organisms is a promising approach owing to their high tolerance concentrations elements (REEs); however, simultaneous removal both REEs and ammonium generally hindered since most are positively charged. Accordingly, immobilization Galdieria sulphuraria (G. sulphuraria) by calcium alginate improve its affinity charged has been used for bioremoval ammonium. The results indicate that 97.19%, 96.19%, 98.87% La, Y, Sm,...
This Article reports the facile fabrication of robust and durable superhydrophobic superoleophilic cotton for highly efficient oil–water separation based on combination hydrophobic octadecanoyl chain bonding polymer grafting via surface-initiated atom transfer radical polymerization (SI-ATRP). Octadecanoyl chain-tethered polymer-grafted was obtained by simultaneous treatment with stearoyl chloride α-bromoisobutyryl bromide to generate bearing initiating sites ATRP (C18-Cotton-Br), followed...
Nanohydroxyapatite (n-HAP) as an environmentally friendly adsorbent of heavy metal ions still requires the rational design pore structure and surface characteristic for enhancing their adsorption capacity toward ions. A novel one-step strategy was developed to regulate esterified HAP (n-EHAP) nanocrystals (NCs) by incorporation 2-bromo-2-methylpropionate (2-BrMP) groups on n-EHAP NCs. When using water sole solvent, aggregation NCs became unavoidable because hydrophobic 2-BrMP n-HAP particle...
High oxygen content of microalgae-derived bio-oil limits their direct use in modern motors. In this study, instead noble metal-catalyzed two-step hydrodeoxygenation, MgAl layered double hydroxides/oxides (MgAl-LDH/LDO) with tunable acidic and basic properties are developed for catalyzing the hydrothermal liquefaction (HTL) microalgae to obtain a low content. The results show that both MgAl-LDH3 MgAl-LDO3 enhance O/C production through hydrolysis cellular compounds decarboxylation...
Abstract Hydrothermal liquefaction (HTL) of microalgae for biofuel production is suffering from low bio‐oil yield and high heteroatomic compositions owing to their efficiency selectivity hydrolysis cellular compounds. Hereby we report Keggin‐type (Mo−V−P) heteropolyacids (HPAs)‐catalyzed HTL efficient low‐nitrogen biocrude production. The increases reaction temperature, time, vanadium substitution degrees HPAs are favorable initially, whereas a significant decrease observed the enhanced...
Abstract A new bio‐based plasticizer, VA8‐8, was prepared derived from vanillic acid, and its structure verified by nuclear magnetic resonance. It incorporated into poly(vinyl chloride) (PVC) to replace dioctyl phthalate (DOP), plasticizing performance evaluated. The results indicated that VA8‐8 shows good compatible with PVC resin, has a excellent effect for PVC. When DOP partially or completely substituted the T g value blends dropped 34.6 24.3°C elongation at break increased 196.4%...
Compared to other well-developed synthetic methods, we developed a novel "phase separation inside monomer droplets" strategy in miniemulsion polymerization fabricate hollow mesoporous silica microspheres (HMSMs) with an average diameter of ∼500 nm. This one-step process produced high HMSMs yield and solid content above 3.4%. The flexibility the proposed method was further demonstrated amino groups-modified (HMSM-NH2) via co-condensation tetraethylorthosilicate adding...
