Understanding Ethyl Cellulose (CAS 9004-57-3): Properties and Solubility
NINGBO INNO PHARMCHEM CO.,LTD. offers Ethyl Cellulose (CAS 9004-57-3), a chemical compound whose distinct physical and chemical properties are key to its widespread industrial utility. Understanding its solubility profile is fundamental to leveraging its full potential across diverse applications, from pharmaceutical coatings to industrial adhesives.
Ethyl Cellulose typically presents as a white to light gray, odorless powder or granules. Its density ranges from 1.07 to 1.18 g/mL, and it has a refractive index of approximately 1.47. A critical characteristic is its thermal stability, with a softening point between 100-130°C and a decomposition point around 240-255°C. Importantly, Ethyl Cellulose exhibits low hygroscopicity and low combustibility, contributing to its safe handling and application.
The solubility of Ethyl Cellulose in organic solvents is one of its most defining features. It readily dissolves in a wide array of organic media, including alcohols, ketones, esters, aromatic hydrocarbons, and halogenated hydrocarbons. Common solvents include ethanol, methanol, acetone, ethyl acetate, butyl acetate, toluene, and xylene. This broad solubility allows it to be easily incorporated into various liquid formulations.
For example, a typical recommended solvent system for achieving consistent solutions involves a mixture of aromatic hydrocarbons and alcohols. The precise ratio depends on the specific grade and desired properties, but a combination like 70-90% aromatic hydrocarbon with 10-30% alcohol is often effective. This solubility in ethyl cellulose solvent combinations is critical for creating films and coatings.
While Ethyl Cellulose is insoluble in water and aliphatic hydrocarbons, its compatibility with many other substances is noteworthy. It mixes well with resins, oils, waxes, and plasticizers, allowing formulators to tailor the properties of the final product, such as hardness, gloss, and water resistance. Its compatibility with other celluloses and nearly all plasticizers further enhances its versatility as an additive.
This detailed understanding of its solubility and compatibility is crucial for anyone specifying or using ethyl cellulose for purchase. NINGBO INNO PHARMCHEM CO.,LTD. provides various grades of Ethyl Cellulose, each optimized for specific applications. By understanding these fundamental properties, industries can harness the full potential of this remarkable polymer.
