PVC is one of the commonly preferred thermoplastics. Plasticizing additives or plasticizers are added to break interstrand-dipole interaction in PVC and soften PVC in general. Plasticizers have many applications such as electrical connectors, vinyl floorings, vinyl water stops, toys, bottle caps, and medical devices. Although a great majority of plasticizers are phthalates that harm to environment, Dioctyl terephthalate (DOTP) is known as a non-phthalate plasticizer. DOTP, one of the plasticizers preferred in the industry, is an aromatic terephthalate. There are two main production methods of DOTP; direct esterification and transesterification. In this review, different synthesis reactions of DOTP plasticizer were summarized. Studies have generally focused on different catalysts, solvents, reactant ratios, and reaction conditions such as temperature, pressure, and reaction time in literature. Synthesizing DOTP from scrap PET products is an environmentally friendly manufacturing method. Besides, properties of DOTP plasticized PVC, mainly migration, mechanical and thermal properties, have been reviewed. According to the results, DOTP has high compatibility with PVC, and DOTP plasticized PVC shows good migration, mechanical and thermal properties. DOTP is a promising plasticizer due to having good properties, low production cost, and low toxicity. PVC, yaygın olarak tercih edilen termoplastiklerden biridir. Plastikleştirici katkı maddeleri veya plastikleştiriciler, PVC'de dipol bağlar arası etkileşimi kırmak ve genel olarak PVC'yi yumuşatmak için kullanılmaktadır. Plastikleştiricilerin elektrik konektörleri, vinil zemin kaplamaları, vinil su tutucuları, oyuncaklar, şişe kapakları, medikal cihazlar gibi pek çok uygulaması bulunmaktadır. Plastikleştiricilerin büyük çoğunluğunu çevreye zararlı ftalatlar oluştursa da, Dioctyl tereftalat (DOTP), ftalat içermeyen bir plastikleştirici olarak bilinir. Endüstride tercih edilen plastikleştiricilerden biri olan DOTP, aromatik bir tereftalattır. DOTP'nin doğrudan esterleştirme vetransesterleşme olmak üzere iki ana üretim yöntemi bulunmaktadır. Bu derlemede, DOTP plastikleştiricinin farklı sentez reaksiyonları özetlenmiştir. Literatürde, çalışmalar genellikle farklı katalizör, çözücü, reaktan oranları ve sıcaklık, basınç, reaksiyon süresi gibi reaksiyon koşullarına odaklanmaktadır. Atık PET ürünlerinden DOTP sentezlemek çevre dostu bir üretim yöntemidir. Ayrıca, başlıca migrasyon, mekanik ve termal özellikleri olmak üzere DOTP ile plastikleştirilmiş PVC'nin özellikleri ele alınmıştır. Sonuçlara göre, DOTP, PVC ile yüksek uyumluluğa sahiptir ve DOTP ile Plastikleştirilmiş PVC iyi migrasyon, mekanik ve termal özellikler sergilemektedir. DOTP, iyi özelliklere, düşük üretim maliyetine ve düşük toksisiteye sahip olmasından dolayı gelecek vaat eden bir plastikleştiricidir.

To replace traditional phthalate plasticizers, our previous research revealed that trioctyl citrate (CA) with an alkyl chain containing 8 carbon atoms (C8) exhibited excellent plasticizing properties. In order to delve deeper into the plasticization effects of CA isomers, CA with different side‐chain structures (C8‐Line, C8‐Branch, and C8‐Star) were synthesized by esterification reactions, and various CA/polyvinyl chloride (PVC) composite films with different CA contents were prepared using a solution casting method. The plasticization mechanisms of these isomers were systematically explored through experimental and molecular dynamics simulations. The results indicate that C8‐Branch demonstrates the optimal plasticizing effect, followed by C8‐Line, while C8‐Star exhibits poorer performance. The C8‐Branch/PVC composite system displays the best plasticizing effect, attributed to the strong interaction forces between the Cl atoms of PVC and the COO groups of CA. On the contrary, the formation of stable dipole pairs between C8‐Star and PVC is impeded by steric hindrance effects. The interaction between the two is predominantly dependent on the intertwining of the alkyl chains in C8‐Star with the PVC chains, also elucidating the observed higher migration rate in the C8‐Star/PVC system. This study provides technical guidance and theoretical basis for the optimized design of high‐performance CA/PVC composites.
