Usage

Chemical Properties

Liquid.Soluble in water 0.16% by weight. Combustible.

Uses

Plasticizer.

General Description

Liquid. Specific gravity 1.05. Boiling point 412°F. Flash point below 141°F. Slightly soluble in water. Used as a plasticizer. Direct contact should be avoided.

Air & Water Reactions

Flammable. Slightly soluble in water.

Reactivity Profile

Esters, such as glycol dipropionate, react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.

Health Hazard

Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.

Intramolecular Hydrophobic Association of Two Alkyl Chains of Oligoethylene Glycol Diethers and Diesters in Water

The octanol-water partition coefficients P of CnH2n+1O(CH2CH2O)mCnH2n+1 and CnH2n+1COOCH2CH2OCOCnH2n+1 are measured and analized on the basis of an empirical linearity between cavity surface area S and hydrophobicity.The slope a of log P vs. total alkyl chain length nt plots of these double chain compounds is smaller than that, aI, of oligoethylene glycol monoethers.The slope of log P vs. m plots at constant n is dependent on n and m for these diethers but is independent of n and m for the monoethers.These facts suggest that two alkyl chains of the diethers associate intramolecularly in water.As the distance d between two alkyl chains in the all-trans arrangement decreases, S of a solute molecule decreases.On the basis of the above results and the conformations of related compounds, several conformations of diethylene glycol diethers in water can be considered and the most probable conformation of ROCH2CH2OCH2CH2OR is suggested as follows: tggttg'g't.The conformations of ethylene glycol diethers and diesters are also suggested.

Method for preparing amino alcohol derivative

The invention provides a method for preparing an amino alcohol derivative. The method is characterized in that substitution reaction is carried out on ester groups of dihydric alcohol carboxylic esteror polyhydric alcohol carboxylic ester to obtain the amino alcohol derivative, wherein the amidogen is derived into sulfonamido, and at least one carboxylic ester group remains. The method for preparing the amino alcohol derivative has the advantages that the raw materials are cheap and obtained easily, the use quantity of catalysts is low, the reaction condition is simple, and the selectivity ofproducts is high.
