Uses

Used in Plastics Industry:
TBC is used as a plasticizer for improving the flexibility and durability of PVC materials, such as food packaging, medical devices, and toys. It is valued for its low volatility, good heat stability, and compatibility with many other plasticizers.
Used in Personal Care Products:
TBC is used as a solvent and a fragrance ingredient in personal care products, often chosen for its low toxicity and minimal environmental impact.
Used as a Safer Alternative:
TBC is considered a safer alternative to phthalate plasticizers, making it a popular choice for applications where low toxicity and minimal environmental impact are desired.

Sulfonated graphene as highly efficient and reusable acid carbocatalyst for the synthesis of ester plasticizers

Plasticizers are well known for their effectiveness in producing flexible plastics. The automotive, plastic and pharmaceutical industries, essential to a healthy economy, rely heavily on plasticizers to produce everything from construction materials to medical devices, cosmetics, children toys, food wraps, adhesives, paints, and 'wonder drugs'. Although H2SO4 is commonly used as commodity catalyst for plasticizer synthesis it is energy-inefficient, non-recyclable, and requires tedious separation from the homogeneous reaction mixture resulting in abundant non-recyclable acid waste. In this study, for the first time, we report an efficient synthesis of ester plasticizers (>90% yields) using sulfonated graphene (GSO3H) as an energy-efficient, water tolerant, reusable and highly active solid acid carbocatalyst. The hydrothermal sulfonation of reduced graphene oxide with fuming H2SO4 at 120°C for 3 days afforded GSO3H with remarkable acid activity as demonstrated by 31P magic-angle spinning (MAS) NMR spectroscopy. The superior catalytic performance of GSO3H over traditional homogeneous acids, Amberlyst-15, and acidic ionic liquids has been attributed to the presence of highly acidic and stable sulfonic acid groups within the two dimensional graphene domain, which synergistically work for high mass transfer in the reaction. Furthermore, the preliminary experimental results indicate that GSO3H is quite effective as a catalyst in the esterification of oleic and salicylic acid and thus may pave the way for its broad industrial applications in the near future.

COMPOSITIONS CONTAINING TETRAHYDROFURFURYL AND/OR ALKYL-SUBSTITUTED TETRAHYDROFURFURYL ESTERS OF CITRIC ACID

Compositions containing tetrahydrofurfuryl and/or alkyl-substituted tetrahydrofurfuryl esters of citric acid are provided. These esters of citric acid can be formed from renewable materials and can be used, for example, as plasticizers for various polymeric materials. The tetrahydrofurfuryl and/or alkyl-substituted tetrahydrofurfuryl esters of citric acid typically have a low odor, have good compatibility with a variety of polymeric materials, and can be used at temperatures often encountered during hot melt processing of polymeric materials.
