What reading level is Rubber Its Production Chemistry And Synthesis in the Light of Recent book?
To quickly assess the difficulty of the text, read a short excerpt:
, to which he gives the formula C 9 H 12 0, . Based on the following analytical results : C = 78-18 ; H = 9-19 ; = 12-63 per cent.
Different results were obtained by Alexander, whose analytical figures, for the substance melting at 161 C. Were : C = 84-25 ; H = 11-41 ; = 4-34 per cent. From these he deduced the formula (C 10 H 16 ) 5 2 .
Tschirch and Miiller 2 have given identical figures for a resin separated from Mozambique balls. These substances would appear to be oxidation pro- ducts of ru...bber and not true resins ; their molecular weight is 712. Hinrichsen and Marcusson are not of this opinion, believing it to be more reasonable to suppose that the substance is an alcohol of the cholesterol series, such as. Phytosterol. Our own experiments lead us to the same conclusion. One must, indeed, expect to meet with products of this kind in vegetable juices.
In Euphorbia rubber Cohen 3 found 7 per cent, of resins ; the alcoholic extract contains /?-amyrine acetate, and a derivative of phytosterol of the- composition C3 H 30 0, 2H 2 ; this does not yield lupeol on saponification, but a phytosterol C 22 H 40 0, H 2 0, closely allied to the isocholesterol of wool fat ; it crystallises in needles from acetone.
