Seccotine originated in Ireland and was first marketed and patented in 1894 by John Stevenson MA (1851-1931). The original manufacturer was the commercial printing company McCaw, Stevenson & Orr Limited of Belfast (founded 1876).
For example, the loss of blue color in leuco-methylene blue is selective for hydrogen peroxide. [21] Quantitative analysis of hydroperoxides can be performed using potentiometric titration with lithium aluminium hydride. [22] Another way to evaluate the content of peracids and peroxides is the volumetric titration with alkoxides such as sodium ...
Mucilage mixed with water has been used as a glue, especially for bonding paper items such as labels, postage stamps, and envelope flaps. [7] Differing types and varying strengths of mucilage can also be used for other adhesive applications, including gluing labels to metal cans, wood to china, and leather to pasteboard. [ 8 ]
Krazy Glue, a super-strong, fast-drying instant adhesive, was introduced to the North American market in 1973. It is based on ethyl cyanoacrylate and has properties similar to other cyanoacrylate adhesives (commonly sold as "Crazy Glue" or "Super Glue"). X-Acto is the brand name for a variety of cutting tools and office products.
Hydrogen peroxide works best as a propellant in extremely high concentrations (roughly over 70%). Although any concentration of peroxide will generate some hot gas (oxygen plus some steam), at concentrations above approximately 67%, the heat of decomposing hydrogen peroxide becomes large enough to completely vaporize all the liquid at standard pressure.
A closely related mixture, sometimes called "base piranha", is a 5:1:1 mixture of water, ammonia solution (NH 4 OH, or NH 3 (aq)), and 30% hydrogen peroxide. [2] [3] As hydrogen peroxide is less stable at high pH than under acidic conditions, NH 4 OH (pH c. 11.6) also accelerates its decomposition.
[12] [14] Bisphenol A Diglycidyl ether-based epoxy coatings are extensively used for coating the inside of cans which come into contact with food and are thus food contact materials. The materials and analogues and conjugates have been extensively tested for and analytical methods developed.
Usual flour bleaching agents are: . Organic peroxides (benzoyl peroxide); Calcium peroxide; Chlorine; Chlorine dioxide; Azodicarbonamide; Nitrogen dioxide; Atmospheric oxygen, used during natural aging of flour
