Flammability of xylene
WebFlammability is the ease with which a combustible substance can be ignited, causing fire or combustion or even an explosion. The degree of difficulty required to cause the combustion of a substance is quantified through fire testing. Internationally, a variety of test protocols exist to quantify flammability. WebIt is in the positions of the two methyl groups, their arene substitution pattern, that it differs from the other isomers, o -xylene and m -xylene. All have the same chemical formula C 6 H 4 (CH 3) 2. All xylene isomers are colorless and highly flammable. The odor threshold of p -xylene is 0.62 parts per million (ppm). [11] Production [ edit]

WebAug 10, 2024 · Yes, xylene is a relatively flammable liquid that catches flames readily in the right conditions (in the presence of naked flames, sparks, or high heat). At extremely high temperatures, xylene can explode. And if stored in closed compartments, xylene can easily form an explosive air mixture or vapor capable of igniting.
