Diethylene glycol and maleic anhydride are used as raw materials to prepare bismaleic acid dibasic acid without catalyst. This intermediate product reacts with pentaerythritol (PER) to obtain bismaleate pentaerythritol (MDPP) as an auxiliary heat stabilizer. The structure of the product was verified by Fourier IR test and hydrogen nuclear magnetic spectrum anal. The ether bond, ester group, carbon-carbon double bond, polyol, and other characteristic structures contained in the mol. can improve thermal stability. Therefore, it can be used as an auxiliary heat stabilizer for PVC and used in combination with the main heat stabilizer. In order to verify the thermal stability performance and further analyze the thermal stability mechanism, testing methods such as thermal aging, Congo red, thermal weight loss, and elec. conductivity were adopted. The results show that when MDPP is added together with calcium/zinc stearate, the thermal stability of PVC is the best. The initial whiteness can reach 40 min, and the static stabilization time is 65 min, which is 15 min higher than the PVC sample with PER and calcium/zinc stearate. It can be seen that MDPP has greatly improved performance compared with the com. auxiliary heat stabilizer PER. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Related Products of 111-46-6).
2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Related Products of 111-46-6
