Renewable malic acid-based plasticizers for both PVC and PLA polymers
Acetylated malic acid alkyl esters (AcMAE-Cn) with different alkyl chain lengths, as alternative plasticizers for both poly (vinyl chloride) (PVC) and poly (lactic acid) (PLA), were synthesized by the esterification of renewable malic acid with alcohols and subsequent acetylation.

Renewable Malic Acid-based Plasticizers for Both PVC and PLA Polymers
It was found that plasticizers (AcMAE-C4 and AcMAE-C6) bearing short alkyl groups (n-butyl and n-hexyl, respectively) may act as excellent plasticizers. In summary, the AcMAE-C6 plasticizer...
Renewable malic acid-based plasticizers for both PVC and PLA polymers
Abstract: Acetylated malic acid alkyl esters (AcMAE-Cn) with different alkyl chain lengths, as alternative plasticizers for both poly (vinyl chloride) (PVC) and poly (lactic acid) (PLA), were synthesized by the esterification of renewable malic acid with alcohols and subsequent acetylation. The molecular structure of the synthesized
- Is malic acid a suitable raw material for PVC and PLA plasticization?
- Accordingly, malic acid is a good candidate and was chosen as the raw material for PVC and PLA plasticization, as it possesses the ester groups required for compatibility and additional reactions can be performed to add alkyl chains to the molecule.
- Is lactic acid based plasticizer suitable for PVC and PLA?
- In this paper, a lactic acid based plasticizer suitable for PVC and PLA was synthesized by a two-step esterification reaction with lactic acid as the main raw material, and compared with commercial plasticizers dioctyl terephthalate (DOTP), diisononyl cyclohexane dicarboxylate (DINCH) and diethylene benzoate (DEDB).
- Can malic acid be plasticized?
- Malic acid with two carboxylic acids and one hydroxyl group is a good candidate for PVC and PLA plasticization, as the two carboxylic acid groups can be esterified to form esters with carbon chains of a chosen length. Another ester group can be formed through the acetylation of the alcohol group, giving the compound a total of three ester groups.
- Is malic acid a scalable and non-toxic material?
- Malic acid, known as a top promising renewable chemical, is a scalable and non-toxic material , . Malic acid with two carboxylic acids and one hydroxyl group is a good candidate for PVC and PLA plasticization, as the two carboxylic acid groups can be esterified to form esters with carbon chains of a chosen length.
- Are plasticizers compatible with water based and acidic food?
- From Fig. 13 (a) (b), it can be seen that within 240 h, all plasticized PVC films could maintain low mass loss in deionized water and 3% (W/V) acetic acid solution, all within the safe range of 5%. These results indicate that the four plasticizers were closely compatible with PVC matrix when they were in contact with water-based and acidic food.
- Which plasticizer has the best plasticizing effect on PVC and PLA films?
- According to the above Tg results of plasticized PVC and PLA films, the AcMAE-C6 plasticizer exhibited the best plasticizing effect on PLA films as well as PVC films, and this phenomenon seems to be due to the structure of AcMAE-C6 having the best compatibility with both PVC and PLA.
