The chief use of p-xylene-2-sulfonic acid is as a reagent to determine serum cholesterol levels. If two substances form a layer, they are clearly immiscible. In tissue processing, tissue has to be embedded in a medium (such as paraffin) to support it and allow it to be cut without damaging the tissue. [21], Xylenes are metabolized to methylhippuric acids. WebThe most common determination of miscibility is by visual evaluation. Aryl sulfonic acids are produced by the process of sulfonation. Xylenes structure consists of two methyl groups attached to a six-carbon ring. Similarly the sulfonyl chloride derived from polyethylene is hydrolyzed to the sulfonic acid. Oral LD50 for rats is 4300mg/kg. In this way it could be soluble with lipids in the membranes of neurons, and could affect neuronal proteins as a result. It is listed as a sulfonic acid and is considered a In amine solutions and hydrocarbons in water but not xylene I recall, the isomer is!
