Pyruvic nitrile, or acetyl cyanide, CH 3 CO.
The half nitrile of malonic acid is cyanacetic acid, CN CH 2 COOH, which, in the form of its ester, may be obtained by the action of a solution of potassium cyanide on monochloracetic acid.
The true nitrile of malonic acid is methylene cyanide, CH 2 (CN) 2, which is obtained by distilling a mixture of cyanacetamide and phosphorus pentoxide.
This compound combines with hydrocyanic acid to form a nitrile which hydrolyses to dichlorhydroxy iso-butyric acid.
Held synthesized the acid from ethyl chlor-acetoacetate (from chlorine and acetoacetic ester) by heating with potassium cyanide and saponifying the resulting nitrile.
His earlier work included an investigation of succinic acid, and the preparation of phenyl cyanide (benzonitrile), the simplest nitrile of the aromatic series; but later his time was mainly occupied with questions of technology and public health rather than with pure chemistry.
Wohl forms the oxime and converts it into an acetylated nitrile by means of acetic anhydride and sodium acetate; ammoniacal silver nitrate solution removes hydrocyanic acid and the resulting acetate is hydrolysed by acting with ammonia to form an amide, which is finally decomposed with sulphuric acid.
CH 2 OH CH20H CH20H CH20H (CH OH) 3 -> 01 OH) 3 -> (CH OH) 3 --> (CH OH)3 CH OH CH OH CH OH CHO CHO CH:NOH CN Hexose -p Oxime -> Nitrile -> Pentose.
This reaction shows that the alkyl or aryl group is attached to the carbon atom in the nitrile.
Its nitrile (prussic acid) has an acid character, a property not possessed by the nitriles of the other members of the series; and, by the abstraction of the elements of water from the acid,.
With urea it gives " /CH NN quinazolone I, and with mandelic nitrile and its H /C0 homologues it forms oxazole derivatives (S.
a-Naphthoic acid, C 1 oH 7 CO 2 H, is formed by hydrolysis of the nitrile, obtained by distilling potassiuma-naphthalene sulphonate with potassium cyanide (V.
It forms needles which melt at 160° C. (3-Naphthoic acid, obtained b y boiling 0-methylnaphthalene with dilute nitric acid, or by hydrolysis of its nitrile (formed when formyl-0-naphthalide is heated with zinc dust), crystallizes from alcohol in needles which Nitrosonaplithols or naphthoquinone-oxames, C 1 oH 6 (OH)(NO) or melt at 184° C. C 1 oH 6 (: NOH): 0.
It also unites directly with hydrocyanic acid to form the nitrile of a-oxyisobutyric acid.
Water converts the former into ammonium thiophosphate, PO(SNH4)3.H20, whilst the latter heated to 300° in a vacuum gives thiophosphoric nitrile, NP:S (Stock, ibid., 1906, 39, p. 1967).
Cyclo-propane carboxylic acid, C 3 H 5 CO 2 H, is prepared by heating the 1.1- dicarboxylic acid; and by the hydrolysis of its nitrile, formed by heating y-chlorbutyro-nitrile with potash (L.
hydrolysis of a nitrile produces a carboxylic acid ' .
making a nitrile by this method is a useful way of increasing the length of a carbon chain.
nitrile rubber palm gives an exceptionally fine ' feel ' whilst protecting your hands.
nitrile gloves are more difficult to sterilize than latex.
nitrile rubber plant as part of this program.
nitrile coatings are very flexible affording better sensitivity and feel.
nitrile rubber sole which offers comfort and enhanced traction poolside.
nitrile molecules start to get in the way.
It shows characteristic ketone reactions, yielding a bisulphite compound and combining with hydrocyanic acid to form the nitrile of a-oxyisosuccinic acid.
Wieland and his collaborators regard " glyoxime peroxide " as an oxide of furazane (q.v.), and have shown that a close relationship exists between the nitrile oxides, furoxane, and fulminic acid (see Ann.
It forms needles which melt at 160Ã‚° C. (3-Naphthoic acid, obtained b y boiling 0-methylnaphthalene with dilute nitric acid, or by hydrolysis of its nitrile (formed when formyl-0-naphthalide is heated with zinc dust), crystallizes from alcohol in needles which Nitrosonaplithols or naphthoquinone-oxames, C 1 oH 6 (OH)(NO) or melt at 184Ã‚° C. C 1 oH 6 (: NOH): 0.
Water converts the former into ammonium thiophosphate, PO(SNH4)3.H20, whilst the latter heated to 300Ã‚° in a vacuum gives thiophosphoric nitrile, NP:S (Stock, ibid., 1906, 39, p. 1967).
The corresponding oxyacid is obtained by the hydrolysis of the nitrile, which is formed by the addition of hydrocyanic acid to suberone (A.
