NOVELTY - An igniting liquid comprises gamma-Valerolactone (50-100 wt.%).    USE - As an igniting liquid or igniting liquid additive, where the igniting liquid is used for grilling or a liquid for illumination (claimed), and also for triggering the ignition of various materials, primarily when grilling, and applied as an illuminating liquid in lamps and tea-lights.    ADVANTAGE - The gamma-Valerolactone is excellently applicable as an igniting liquid or igniting liquid additive; avoids burns, that when the flame is positioned above the liquid, gamma-Valerolactone does not burst into flames, this only happens when the surface of the liquid is touched with the match flame and even then it is not ignited suddenly with a huge flame, but it starts to burn slowly and steadily on the whole surface; has high oxygen content, thus burns without generating smoke and soot, contrary to hydrocarbon based igniting liquids which emit a heavy dose of soot due to imperfect burning; has low vapor pressure, thus does not evaporate quickly, its odor is pleasant and sweetish, hence it does not spoil the flavor of grilled food either; and is not harmful to health since it is found in fruit also, and it is used by the food industry as a food additive. Because gamma-Valerolactone generated from renewable base materials, its application does not contribute to carbon-dioxide emission, in fact it reduces emission coming from the use of barbeques and this is an important environmental benefit in light of the large number of users. Since a lit match failed to ignite the gamma-Valerolactone liquid film on a charcoal surface even from a distance of a few millimeters, it seemed to be expedient to mix it with a low volume of another higher vapor pressure component, which accelerates the ignition of gamma-Valerolactone without contact. The present igniting liquid preferably contains alcohol (up to 50, preferably 1-25 wt.%) thus provides combined favorable characteristics of the ingredients. Gamma-Valerolactone found in fruit and also applied as a food additive in food industry is one of the most important raw materials, because it is used for turning out energy and carbon-based products, is produced from carbohydrates, and stored and transported easily and safely, because it has a low freezing point, and high boiling and flash points.
