  Treating agent for cellulosic textile material and process for treating cellulosic textile material - Patent 5695528
The treating agent eliminates the necessity of the use of a substance releasing formaldehyde during wash and wear treatment and enables non-formaldehyde wash and wear treatment, and the cellulosic textile material treated by the treating agent is completely free from formaldehyde, retains enough of the strength thereof, and undergoes neither discoloration nor fibrillation.
The process of claim 4, wherein the water-soluble phosphonium salt of a phosphorous-containing oxoacid and the polycarboxylic acid are each present in the treating agent in an amount of from 1 to 25% by weight based on the weight of the cellulosic textile material.
The amount of the water-soluble phosphonium salt of a phosphorus-containing oxoacid to be added on the textile material is generally from 1 to 25% by weight, preferably from 3 to 13% by weight, based on the amount of the textile material to be treated.

 Oxoacid - Wikipedia, the free encyclopedia
An oxoacid is an acid which contains oxygen.
Generally, oxoacids are simply polyatomic ions with a hydrogen cation.
However, boric acid is usually considered to be an oxoacid nonetheless.

 Gas generator compositions - Patent 5656793
A gas generator contains hydrazodicarbonamide serving as a reducing agent, oxoacid salt serving as an oxidizing agent, and a combustion controller which is catalytic or combustible.
The oxoacid salt used as an oxidizing agent may be an oxohalogeno acid salt, a nitrate or an oxo metal acid salt.
In addition, surplus oxoacid salt which was not used during the combustion of HDCA is decomposed during combustion and produces oxygen gas.

 Oxoacid Formulas
The formulas for the oxoacids of the p-block elements, shown in Table 1, do not seem to "make sense" in the same way that do formulas of halides and hydrides (with the exception of boron hydrides).
Similarly, it is puzzling that the highest-oxidation-state oxoacid of N is HNO
Although oxoacid formulas may be rationalized in terms of Lewis structures, VSEPR, and orbital hybridization ideas, to predict the formulas in Table 1 is more challenging.

 [No title]
Oxoacids: Oxoacids are acids that contain three elements, one of which is oxygen.
Oxoacids are named by comparing the given oxoacid to the "model" acid for the particular periodic group of which given oxoacid is a member.
In this case, the oxoacid is named with an -ic suffix but the acid is not considered to be the "model" for the group.

 Duran: Chapter Three Oxoacids   (Site not responding. Last check: 2007-10-11)
Among the most important acids in water are those that donate protons from a hydroxyl group (-OH).
One class of such a hydroxyl group acid is the oxoacids, in which the acid proton is on a
Also, as is covered in the previous section, how to name a member of a given oxoacid series when you are given another member of that series name and oxidation state.

 Amidine - Wikipedia, the free encyclopedia
The oxoacid from which an amidine is derived must be of the form R
When the parent oxoacid is a carboxylic acid, the resulting amidine is a carboxamidine, and has the following general structure:
Carboxamidines are frequently referred to simply as amidines, as they are the most commonly-encountered type of amidine in organic chemistry.

 Lewis Structures' Tutorial: Part 8- Oxoacids
An oxoacid (or oxyacid) is an acid composed of hydrogen, oxygen, and another element.
One way to recognize an acid from the chemical formula is that it's written as "H-something".
Let's go ahead and go through the entire process of drawing the Lewis structure for sulfuric acid before we move on to another structure.

 Periodic Trends and Oxides
If the reaction with water produces a moderately acidic oxoacid, the oxide may or may not be soluble.
If the oxoacid generated is weakly acidic, the oxide is usually but not always insoluble in water.
Some acidic oxides such as those of sulfur and nitrogen are air pollutants because they react with moisture in the air to produce acid rain.

 Lewis Structures - Title
In the case of the oxoacids, the situation gets a little bit more complex, since the definition of an oxoacid implies that the hydrogen (s) are bonded to an oxygen atom, therefore, same situation applies, the hydrogen (s) are listed first, followed by the central atom and finally the oxygens.
Remember that this molecule is an oxoacid, so the hydrogen must be attached one
Therefore we must take a pair of electrons from either oxygen atom not bonded to the hydrogen and form a double bond between N and O, to satisfy nitrogen's octet

 Carboxylic Acids and Derivatives
Acyl intermediates include acyl anions, acyl radicals and acyl cations (synonym: acylium ions) which are formally derived from oxoacids R
Acyl anions, radicals and cations can formally be represented by canonical forms having a negative charge, an unpaired electron or a positive charge on the acid-generating element of the oxoacid.
An ambiguous term, which may imply either a higher oxidation state of a central atom, as in perchloric acid, or a derivative of hydrogen peroxide, as in CH Accordingly, it is not recommended as a class name.
