Methanediol, also known as formaldehyde monohydrate or methylene glycol, is an organic compound with chemical formula CH 2 (OH) 2. It is the simplest geminal diol . In aqueous solutions it coexists with oligomers (short polymers).
Water Conditioner. These are designed to balance the "hardness" of water (the presence of other trace chemicals that change the water's pH or neutrality) and to help reduce the deceased's acidity, a by-product of decomposition, as formaldehyde works best in an alkaline environment. Additionally, water conditioners may be used to help inactivate ...
Conversely, a keto group can combine with water to form the geminal hydroxyl groups. The equilibrium in water solution may be shifted towards either compound. For example, the equilibrium constant for the conversion of acetone (H 3 C) 2 C =O to propane-2,2-diol (H 3 C) 2 C(OH) 2 is about 10 −3, [1] while that of formaldehyde H 2 C =O to ...
Propane-2,2-diol, an example of a geminal diol. A geminal diol has two hydroxyl groups bonded to the same atom. These species arise by hydration of the carbonyl compounds. The hydration is usually unfavorable, but a notable exception is formaldehyde which, in water, exists in equilibrium with methanediol H 2 C(OH) 2
Formaldehyde (/ f ɔːr ˈ m æ l d ɪ h aɪ d / ⓘ for-MAL-di-hide, US also / f ə r-/ ⓘ fər-) (systematic name methanal) is an organic compound with the chemical formula CH 2 O and structure H−CHO, more precisely H 2 C=O.

Respiratory virus season is officially here in the U.S., making it a prime time to catch a cold. And because the average adult gets two or three colds a year, you could be dealing with an ...
The uppers are even treated with a water-repellent coating to make this style a wardrobe workhouse. While the almond toe shape of the boot makes for a chic look, it may be too narrow for certain ...
