pH & d-Limonene

 

A Note about pH measurement and d-Limonene:

In general, the standard pH test assumes an aqueous solution (water based). The pH of water immiscible solvents (d-Limonene) cannot be measured using typical methods. The chemistry of organic solvents prevents accurate measurements using the 0-14 scale and standard electrodes.

A “relative” pH measurement is obtained by mixing the oil with an equal volume of neutralized water (preferably purified with no dissolved salts). The pH of the water should be measured before mixing. Mix the water and oil for approximately 5 minutes and then allow the phases to separate. Measure the pH of the water phase again. In principle, the pH of the water is now a reflection of the pH of the oil. This is not a precise value, but can be used as an estimation for most applications. Due to the nature of citrus processing, d-Limonene typically contains residual amounts of anhydrous acids and thus yields an acidic “relative” pH value. The most common problem associated with the pH issue is when water collects at the bottom of vessels containing d-Limonene. The d-Limonene is replenished based on the process, but the water is stagnant and continues to become more acidic over time. This can cause corrosion problems.

 

Florida Chemical does offer a neutralized grade of d-Limonene at additional cost.

Florida Chemical delivers a stable, high-quality citrus oil supply because we have a long-established position within the citrus industry. Not only do we provide you with environmentally responsible products—we are a supply partner that you can count on.

Last week, Immigration and Customs Enforcement refused to extend my stay of deportation. I sought sanctuary in the church because, like that of millions of other immigrants, my future in this cialis from canada was thrown into doubt. Thanks to President new policy, every undocumented person is a priority for eviction from this country.

 

d-Limonene Manufacturing

d-Limonene is the major component of the oil extracted from the citrus rind during the citrus juicing process. When the fruit is juiced, the oil is pressed out of the rind, then separated from the juice and distilled to recover certain flavor and fragrance compounds.

After the juicing process, the peels are conveyed to a steam extractor. When the steam is condensed, a layer of oil floats on the surface of the condensed water. This removes the bulk of the oil from the peel.

Food Grade d-Limonene is extracted through the juicing process and Technical Grade d-Limonene is removed through the peel steam extraction process.
