Flash Point Of Solvents Pdf Viewer

The invention pertains to the field of organic solvents.

More particularly, the invention pertains to adding a combination of terpene alcohols to volatile organic compounds to increase their flash points and expand the uses for which these volatile solvents can be used.

Organic solvents, such as acetone, xylene, ketones, aromatic hydrocarbons, such as benzene, esters, aliphatic hydrocarbons and ethers are widely used as additives for industrial and commercial purposes. Due to the high volatility of these compounds, their uses are regulated by many countries' governmental agencies.

Obviously, the more flammable a solvent, the more restrictions exist on its use. Further, manufacturers that utilize solvents must handle the more flammable liquids more carefully and have to address issues involving atmospheric volatility and worker health concerns due to excessive exposure to these chemicals. If these solvents can be modified so that their flash points can be increased, this would result in significantly more uses for these compounds as well as increasing their shelf lives.

It is desirable therefore to increase the flash point of a variety of solvents without substantially increasing the cost of the solvent while maintaining the solvent and its utility and effectiveness for its purpose. It is known that terpene alcohols can be added to volatile organic solvents to increase the flash points of these solvents. Many terpene alcohols have the chemical formula: C10H18O.

Terpenoid is the general name given to this class of compounds which are characterized by a repeating carbon skeleton of isoprene. Terpenoids are derived from plants, trees, flowers and other vegetation.

They come in the form of liquids, solids, waxes, oils and alcohols. Terpenoids are divided into groups determined by the number of carbon atoms and repeating isoprene units.

They may be formed as acyclic, monocyclic or polycyclic structures.

Terpene alcohols in various forms have been used for centuries in fragrances due to their compatibility with other compounds and their minimal negative environmental impact. The flavor and fragrance industries divide terpineols, which are a type of terpene alcohol, into Alpha-, Beta- or Gamma-Terpineols, with Beta-Terpineol being non-naturally occurring. Terpene alcohols have been used for other purposes, such as disinfectants, cleaning compounds, soaps, cosmetics and colognes.

They are also known to add, enhance or mask the odor of products which perhaps might be offensive to humans or animals. This is a costly method to raise flash points.

The excessive loading of a single alpha terpineol results in paint and adhesive formulation problems from incompatibility with some key resins particularly during film formation and drying. The Acetone evaporates, leaving the heavy loading of terpineol behind. The terpineol acts as a diluent, phase separates, forming under the film, within the film, and upon the surface. The result for fast drying lacquers, vinyls, and similar coatings was complete rejection of the coating by the substrate.

After days of drying time the stressed films lifted and floated, having no adhesion or bond strength. Vinyls heavily loaded with terpineol perform the worst, because they are in solution and exhibit a low mole wt. As soon as the Acetone evaporates 15 min , the film becomes stressed due to the higher mole wt. In this instance, a heavy loading of terpineol acts like a parting agent or wax thus preventing adhesion of the film to the substrate.

The flash points of volatile organic compounds are raised by using a minimal amount of terpene alcohols to allow the blended compound to have a higher flash point. This is achieved by using a low concentration of two or more terpene alcohols.

This permits more uses for the VOC than would otherwise be expected based on their pure flash point. By adding only from about 0. From about 0.

It has been discovered that lower amounts of terpene alcohols added actually improves the performance of the resulting compound in contrast to adding a significantly higher amount of terpene alcohols.

An added benefit is that since terpene alcohols can be expensive, the less used, the less expensive is the ultimate compound. Examples of terpene alcohols include geraniol, citronellol, nerol, menthol, nerolidol and farnesol.

These compounds can be acquired from manufacturers such as Flavors and Fragrances, Inc. Other compounds that can be used with this invention include acetates and esters. For example, these combination compounds can now successfully be used for expanded uses in the following industries.
