As expected from the Lewis acidity of Ti4+, the titanosilicates strongly adsorb and oxidize basic nitrogen-containing compounds with a lone pair of electrons localized on the N atom. By contrast, nitrogen oxides (NOx) and nitro compounds... 

Many oxides of metals that have a +1 or +2 charge are called basic oxides (basic anhydrides), because they will react with acids.

About 100 fungicides me required for these various uses in the United States. The principal ones are sulfur, liine-sulfur (polysulfides of calcium) copper sulfate (or ils equivalent in the oxides, basic sulfates, oxychloride and other relatively insnluhle copper compounds) creosote products and zinc chloride, both used as wood preservatives and a wide variety of organic compounds. Among the latter are several dithiocarbamates. such as ferbam and zineb, and other thio compounds, like N-(trichloronielhyllhio>-phthalimide (folpel) cis-NfI Irtchloroniclhy] Jthio)-4-cyclohexane- 1.2-dicaiboxyimide (captan) and 8-hydroxyquinoline. 

The two polymers most often used in these applications are dextran and PEG. Both polymers consist of repeating units of a single monomer—glucose in the case of dextran and an ethylene oxide basic unit in the case of PEG. The polymers may be composed of linear strands (PEG or dextran) or branched constructs (dextran). An additional similarity is that both of them possess hydroxyl and ether linkages, lending hydrophilicity and water solubility to the molecules. Dextran and PEG can be activated through their hydroxyl groups by a number of chemical methods to allow...

Sulphur and oxygen are interchangeable in sulphides and oxides. Metal oxides (basic) and non-metal oxides (acidic) combine to form salts. Likewise metal sulphides may combine with sulphides of weakly metallic or non-metallic elements to form salts, the so-called thio-salts, or sulpho-salts. Thio-salts of a few of the elements, notably tin, are very well defined. Stannous sulphide does not form a thio-salt but addition of sulphur converts it to stannic sulphide which does form a soluble thio-salt with the sulphide of an alkali metal.

Figure 6-8 The normal oxides of the representative elements in their maximum oxidation states. Acidic oxides (acid anhydrides) are shaded red, amphoteric oxides are shaded purple, and basic oxides (basic anhydrides) are shaded blue. An amphoteric oxide is one that shows some acidic and some basic properties.

Another common kind of reaction of oxides is the combination of metal oxides (basic anhydrides) with nonmetal oxides (acid anhydrides), with no change in oxidation states, to form salts.
