Air & Water Reactions

Highly flammable. Water soluble.

Reactivity Profile

3-Ethoxy-1-propanol is an ethoxy-alcohol derivative. The ether is relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

Fire Hazard

3-Ethoxy-1-propanol is combustible.

Dynamical Characterization in Aqueous Solutions of 3-Methoxy- and 3-Ethoxy-1-propanol by Ultrasonic Methods

3-Methoxy-1-propanol and 3-ethoxy-1-propanol were synthesized through potassium propoxide from 1,3-propanediol.Ultrasonic absorptions in their aqueous solutions were measured in the frequency range from 8.5 to 220 MHz as functions of their concentrations along with the sound velocity and density.In a solution of 3-ethoxy-1-propanol, a single relaxational absorption was observed; the cause was attributed to a perturbation of an equilibrium as AB A + B, where AB represents the solute-solvent complex, A the solute and B the solvent molecules.On the other hand, no relaxational absorption was observed in a 3-methoxy-1-propanol solution up to 4 mol dm-3.The thermodynamic and the kinetic parameters were evaluated for the abovementioned process from the concentration dependences of the ultrasonic parameters in a 3-ethoxy-1-propanol solution.From evidence concerning the appearance and disappearance of ultrasonic relaxational absorption and comparisons of the rate and thermodynamic constants in aqueous solutions of various alcohols, the alternation of the water structure affected by the addition of the solutes is discussed in connection with the solute structures.The methoxyl group was explicitly found to act as a water structure breaker and the ethoxyl group to do so slightly.

A liquid phase hydrogenolysis of acetal compounds such as cyclic acetals and cyclic ketals are fed to a reaction zone and reacted in the presence of a noble metal catalyst supported on a carbon or silica support to make hydroxy ether mono-hydrocarbons in high selectivity, without the necessity to use acidic co-catalysts such as phosphorus containing acids or stabilizers such as hydroquinone.

Synthesis and antiproliferative activity of alkylphosphocholines

Alkylphosphocholines (APC) with one or more methylene groups in the alkyl chain replaced by oxygen atoms or carbonyl groups, or both have been assembled modularly using ω-diols as central building blocks. Out of 25 new compounds of this kind, 11 were evaluated for their antiproliferative activity on four cell lines and compared with miltefosine to evaluate their hemolytic activity (HA) and cytotoxicity on non-tumoral cells (MT2), used as markers of adverse effects. Compound 13 was more active on cancer cell lines than on non-tumoral cells and the data were similar for MTT and thymidine incorporation assays. It had less HA than miltefosine. Compound 13 could therefore be a candidate for the preparation of compounds with higher cytotoxicity on cancer cells and lower general toxicity.
