In this work, rosin-based plasticizer was synthesized by Diels-Alder (DA) and esterification. First, the maleopimaric acid (RT) was obtained by DA between the double bond of rosin and maleic anhydride. Then, the carboxyl group and anhydride group of RT was esterified with tetrahydro geraniol to obtain the rosin-based polyacid esters (RTT) under the catalysis of p-toluene sulfonic acid. The structure of RT and RTT was detected by FTIR and 1H-NMR. RTT was used as main plasticizer to obtain plasticized polyvinyl chloride (PVC) materials and compared with DOP. The results showed that RTT improved the thermal stability and reduced Tg of PVC film. Plasticized PVC films had excellent mech. properties with the elastic modulus of -4,793.67 MPa and tensile strength of -111.86 MPa, higher than that of pure PVC and DOP-6. RTT showed better volatility stability, migration, and solvent extraction in PVC compared to DOP. J. VINYL ADDIT. TECHNOL., 2019. © 2019 Society of Plastics Engineers. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8SDS of cas: 106-21-8).
3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.SDS of cas: 106-21-8
