Usage

General Description

Tetraethylene glycol dibutyl ether, also known as butyl carbitol, is a clear, colorless liquid with a faint odor. It is a high boiling solvent with good solvency for a wide range of resins, including nitrocellulose, acrylic, and alkyd resins. It is commonly used as an industrial solvent in processes such as paint and coating formulations, metal cleaning, and as a coupling agent in the production of water-based inks. Additionally, it is used as a dispersant in the agricultural industry and as a hydraulic fluid in aviation. It is considered relatively low in toxicity and is not classified as a carcinogen, mutagen, or reproductive hazard. However, it can cause irritation to the eyes and skin upon contact and should be handled with proper safety precautions.

Process for the preparation of cyclic esters and method for purification of the same

The present invention provides a process for production of a cyclic ester by depolymerization of an aliphatic polyester. In the process, a mixture containing the aliphatic polyester and a specific polyalkylene glycol ether, which has a boiling point of 230-450° C. and a molecular weight of 150-450, is heated under normal or reduced pressure to a temperature at which depolymerization of the aliphatic polyester takes place. Then, a substantially homogeneous solution phase, consisting of the melt phase of the aliphatic polyester and the liquid phase of the polyalkylene glycol ether, is formed. Heating of the solution phase is continued to form the cyclic ester by depolymerization and distil out the cyclic ester together with the polyalkylene glycol ether, and then the cyclic ester is recovered from the distillate. The present invention also provides a process for purification of a crude cyclic ester by use of the specific polyalkylene glycol ether described above.

Phase-Transfer Synthesis of Monoalkyl Ethers of Oligoethylene Glycols

The effects of catalyst, temperature, solvent, and reagent ratios on the phase-transfer-catalyzed Williamson ether synthesis of monoalkyl ethers of oligoethylene glycols have been studied.A convenient method has been developed which gives reproducibly high yields of pure monoethers in the presence of aqueous sodium hydroxide.
