The higher the saponification value, the lower the fatty acids average length, the lighter the mean molecular weight of triglycerides and vice versa. Practically, fats or oils with high saponification value (such as coconut and palm oil) are more suitable for soap making.
The Reichert value is an indicator of how much volatile fatty acid can be extracted from a particular fat or oil through saponification. It is equal to the number of millilitres of 0.1 normal hydroxide solution necessary for the neutralization of the water-soluble volatile fatty acids distilled and filtered from 5 grams of a given saponified fat.
Saponification is a process of cleaving esters into carboxylate salts and alcohols by the action of aqueous alkali. Typically aqueous sodium hydroxide solutions are used. [1] [2] It is an important type of alkaline hydrolysis. When the carboxylate is long chain, its salt is called a soap. The saponification of ethyl acetate gives sodium acetate ...
So bottled water could be produced on a larger scale and grew in popularity. [6] Many saw bottled water as safer than municipal water supplies, which could spread diseases such as cholera and typhoid. [8] By around 1850, one of America's most popular bottlers, Saratoga Springs, was producing more than 7 million bottles of water annually. [6 ...
(The hydroxide solution used in such a titration is typically made from sodium hydroxide, potassium hydroxide, or barium hydroxide.) [1] It is measure of the steam volatile and water insoluble fatty acids, chiefly caprylic, capric and lauric acids, present in oil and fat. The value is named for the chemist who developed it, Eduard Polenske. [2]
"The calculated saponification value is not applicable to fats and oils containing high amounts of unsaponifiable material, free fatty acids (>0.1%), or mono- and diacylglycerols (>0.1%)." This is not true. Saponification value is applicable for any substance which contains saponifiable compounds.
Plastic rings will (hopefully) soon be eliminated. This hack might soon be an unnecessary relic of the past. Fortunately, many brands are making efforts to reduce or eliminate single-use items ...
A case of some merchandise is a collection of items packaged together. A case is not a strict unit of measure. For consumer foodstuff such as canned goods, soda, cereal, and such, a case is typically 24 items, however cases may consist of any quantity depending on manufacturer packaging - cases are typically found in multiples of 4 or 6.
