Needle

OL-crolonic acid. irans-crotonic acid. Colourless needles or large plates m.p. 72 "C, b.p. 180 C. Prepared by the oxidation of... [Pg.115]

Isocroionic acid, -crotonic acid, cis-croionic acid. Colourless needles m.p. 14 C, b.p. 169 C. Prepared by distilling -hydroxy-glutaric acid under reduced pressure. Converted to a-crotonic acid by heating at 180 C, or by the action of bromine and sunlight on an aqueous solution. [Pg.116]

C8H8O4. Colourless needles m.p. 109 C, b.p. 270 C. Prepared by boiling acetoacetic... [Pg.127]

CqHqIaNOi. Pale, straw-coloured needles, m.p. 198 C. Found in certain marihe organisms, such as corals and sponges, and in the thyroid gland. [Pg.139]

Greenish-yellow needles or prisms, m.p. 148-149 C, sparingly soluble in cold water. Gives crystalline condensation products with aldehydes. [Pg.140]

D-fructose, C HijOo. Crystallizes in large needles m.p. 102-104 C. The most eommon ketose sugar. Combined with glucose it occurs as sucrose and rafftnose mixed with glucose it is present in fruit juices, honey and other products inulin and levan are built of fructose residues only. In natural products it is always in the furanose form, but it crystallizes in the pyranose form. It is very soluble in... [Pg.182]

S-hydroxyquinoline, oxine, C9H7ON. Light brown needles, m.p. 15-16 C. Forms insoluble complexes with metals. The solubilities of the derivatives vary with pH, etc. and hence oxine is widely used in analysis. Used for estimating Mg, Al, Zn and many other metals. Many oxinates are extracted and the metal is estimated spectrophotometrically. Derivatives, e.g. 2-meIhyl tend to be specific, for, e.g.. Copper derivatives are used as fungicides. [Pg.212]

C, b.p. 150 C/25mm. Prepared from l-lactic acid. It is partially converted to lactic acid by water. o-Lactide is similar. DL-Lactide crystallizes in colourless needles, m.p. 124-5 "C, b.p. l42°C/8mm. Obtained from DL-lactic acid. [Pg.233]

C12H24O, CH3 [CH,]io COOH. Needles, m.p. 44 C, b.p. 225"C/I00mm. A fatty acid occurring as glycerides in milk, spermaceti, laurel oil, coconut oil, palm oil and other vegetable oils. The metal salts are widely used. [Pg.236]

H2N-CH2 [CH2j3.CH(NH2) COOH. Colourless needles, m.p. 224 C (decomp.), very soluble in water, insoluble in alcohol. L-(-H)-Lysine is one of the basic amino-acids occurring in particularly large quantities in the protamine and histone classes of proteins. It is an essential amino-acid, which cannot be synthesized by the body and must be present in the food for proper growth. It can be manufactured by various fermentation processes or by synthesis. [Pg.244]

Malic acid crystallizes in colourless needles m.p. lOO C. It o- curs in many acid fruits, such as grapes, apples and gooseberries. It can be prepared by microbiological processes using various moulds or from ( + )-bromosuccinic acid by the action of NaOH. [Pg.248]

C]2Hi50]2. Colourless needles m.pr. 286-288°C. When heated it decomposes into pyro mellitic anhydride, water and CO2. Occurs as the aluminium salt (honeystone) in some lignite beds. Prepared by oxidation of charcoal with concentrated nitric acid. [Pg.253]

Bright yellow needles m.p. 45 C, b.p. 2 4°C. Prepared together with 4-nitrophenol by careful nitration of phenol. Sodium sulphide reduces it to 2-aminophenol which is used in dyestuffs and photographic processes. [Pg.279]

Ditrophenol, -nitropbenol, C H NOj. Colourless needles m.p. 114 C. Prepared as 2-nitrophenol. Reduction with iron and hydrochloric acid gives 4-aminophenol. [Pg.279]

C HgNjOjS. Colourless needles, with iH20. Prepared by reducing diazotized sulphanilic acid with an excess of sodium sulphite. It is a typical hydrazine in its reactions with ketones, and with acetoacetic ester. The latter reaction gives rise to the tartrazine dyestuffs, and is much used commercially. [Pg.305]

Colourless needles m.p. 14rC, b.p. 290"C. Slowly hydrolysed to phthalic acid by dilute acids and alkalis. [Pg.313]

CfiHsNjOs. Red needles m.p. 168-169°C. Soluble in dilute acids and alkalis. Prepared by reduction of picric acid with sodium hydrogen sulphide, ft is used for the preparation of azodyes, which can be after-chromed by treatment with metallic salts owing to the presence of a hydroxyl group ortho to the amino-group. [Pg.313]
