Usage

Description

Vanadium dichloride oxide, also known as vanadyl chloride or vanadium oxychloride, is a green, deliquescent crystal with chemical formula VOCl2. It is a transition metal halide that exhibits unique chemical properties, making it a versatile compound in various applications.

Uses

Used in Textile Industry:
Vanadium dichloride oxide is used as a mordant in the printing of fabrics. As a mordant, it helps to fix dyes to the fabric, enhancing the colorfastness and durability of the printed designs.
Chemical Properties:
Vanadium dichloride oxide is a green, deliquescent crystal that can absorb moisture from the air, leading to the formation of a dark-green, syrupy mass. The usual technical product is available in the form of a dark-green, syrupy mass with a purity of 76-82% or as a solution. It is soluble in water, alcohol, and acetic acid, but it should be handled with care as it may react violently with potassium. Additionally, it is slowly decomposed by water, which is an important consideration when using it in various applications.

Hazard

Strong irritant to tissue.

Proof of existence and thermochemical characterization of the gaseous molecule VOCl2

By use of the Knudsen-cell mass spectrometry the existence of VOCl2(g) is proven. Lines of fragmentation are set up for VOCl3(g). The vapor above V2O3(s) with Cl2(g) is examined. The sublimation of VOCl2 is measured at a temperature of 550-620 K. By 2nd law calculations the heat of sublimation is defined. The calculation for the gaseous VOCl2 leads to ΔBH°(VOCl2(g), 298 K) = -(130,4 ± 1,5) kcal · mol-1. The influence of VOCl2(g) for chemical vapor transport reactions of vanadium oxides with Cl2 is discussed by equilibrium calculations. Johann Ambrosius Barth 1996.
