At NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to providing clear and comprehensive information about the chemical compounds we supply. Today, we focus on 1,2-Propanediol Dibenzoate (CAS 19224-26-1), also recognized as Propane-1,2-diyl Dibenzoate. Understanding its core chemical properties is fundamental to appreciating its versatility and efficacy across various industrial applications.

Chemically, 1,2-Propanediol Dibenzoate is a diester formed from propylene glycol and benzoic acid. Its molecular formula is C17H16O4, and it possesses a molecular weight of approximately 284.31 g/mol. The compound presents as a colorless liquid, which is a significant characteristic for applications where visual clarity is important, such as in certain coatings or clear adhesives. Its physical state as a liquid at room temperature aids in its ease of handling and incorporation into liquid formulations.

A critical property of 1,2-Propanediol Dibenzoate is its high solvating power for a wide range of polymers. This makes it an excellent plasticizer, capable of increasing the flexibility and processability of materials like PVC, vinyl acetate, and polyacrylates. Its effectiveness is further demonstrated by its relatively low volatility and excellent compatibility, ensuring that it remains within the polymer matrix, contributing to stable long-term performance.

The chemical structure contributes to its favorable environmental profile. Unlike some traditional plasticizers, 1,2-Propanediol Dibenzoate is generally considered to have low toxicity and is biodegradable. This aligns with the growing industry trend towards sustainable and environmentally conscious chemical solutions. Its designation as a low VOC coalescent further underscores this aspect, making it suitable for formulations adhering to strict emission standards.

Key specifications often associated with 1,2-Propanediol Dibenzoate include its refractive index, density, and boiling point (or decomposition temperature, as it often decomposes before boiling at atmospheric pressure). These parameters are vital for quality control and ensuring consistent performance in manufacturing processes. For instance, its refractive index plays a role in optical properties in certain applications, while its density and viscosity influence flow characteristics.

NINGBO INNO PHARMCHEM CO.,LTD. ensures that the 1,2-Propanediol Dibenzoate supplied meets stringent quality standards. By understanding these detailed chemical properties of 1,2-Propanediol Dibenzoate, formulators can confidently leverage its capabilities to develop advanced, high-performance products across diverse sectors, from coatings and adhesives to plastics and sealants.
