Oxone is a versatile oxidant in organic synthesis. It oxidizes aldehydes to carboxylic acids; in the presence of alcoholic solvents, the esters may be obtained. [9] Internal alkenes may be cleaved to two carboxylic acids (see below), while terminal alkenes may be epoxidized.
The adjacent sheets are held together by hydrogen bonding between the hydroxyl oxygen atoms of one sheet and the opposing chlorine atoms in the other sheets. The resulting weak bonding between the sheets accounts for the perfect (100) cleavage and the typical platy habit of botallackite (Figure 2). Figure 2. Cu coordination and bonding in ...
Poly(p-phenylene oxide) (PPO), poly(p-phenylene ether) (PPE), poly(oxy-2,6-dimethyl-1,4-phenylene), often referred to simply as polyphenylene oxide, is a high-temperature thermoplastic with the general formula (C 8 H 8 O) n. It is rarely used in its pure form due to difficulties in processing.
(Gd0.99, Pr0.01)2O2S sub-microphosphors synthesized by homogeneous precipitation method are very promising for a new green emitting material to be applied to the high resolution digital X-ray imaging field [3] Gadolinium oxysulfide powder phosphors are intensively used for conversion of X-rays to visible light in medical X-ray imaging.
Laundry detergent is manufactured in powder (washing powder) and liquid form. While powdered and liquid detergents hold roughly equal share of the worldwide laundry detergent market in terms of value , powdered detergents are sold twice as much compared to liquids in terms of volume .
The diameter of the powder used is relative to the density (g/m 2) of the stock (paper or board) being printed. For 150 g/m 2 paper the ideal anti-set-off spray powder would be 15 μm in diameter, for 200 g/m 2 20 μm, through to 70 μm for heavy board (700 g/m 2). Most manufactures of spray powder offer both coated and uncoated powders.
Anhydrous ferric hydroxide occurs in the nature as the exceedingly rare mineral bernalite, Fe(OH) 3 ·nH 2 O (n = 0.0–0.25). [4] [5] Iron oxyhydroxides, FeOOH, are much more common and occur naturally as structurally different minerals (polymorphs) denoted by the Greek letters α, β, γ and δ.
Disodium octaborate is traded either as a liquid concentrate, or as the tetrahydrate Na 2 B 8 O 13 ·4H 2 O, a white odorless powder. It is used as an insecticide , [ 3 ] [ 4 ] and as a fungicide and algicide , and as a fire retardant ., [ 5 ] [ 6 ] and as a boron micronutrient additive in fertilizers . [ 1 ]
