N-Amyl thiocyanate

A mixture of 340 ml. of ethanol and 147 g. (1.52 moles) of potassium thiocyanate is heated to reflux, and 157 g. (1.04 moles) of n-amyl bromide is added dropwise. Reflux is continued for 2 hours after completion of the addition of the bromide. Most of the ethanol is removed by distillation, and the residue is diluted with water and extracted with ether. The combined ethereal extracts are dried over calcium chloride, and the ether is removed by distillation. Fractional distillation of the residue at 16 mm. pressure gives an 85% yield of n-amyl thiocyanate, b.p. 90-91°. [Pg.29]

One of the first observations of such stepwise, separate phase transitions of the paraffinic part of an amphiphilic molecule was made on tetra-n-amyl ammonium thiocyanate At 315 K the crystals undergo a major first-order transition [AS = 71 J/(K mol) with a 4.8 % volume change]. The final transition to the isotropic, molten salt at 323 K is entropically smaller [AS. = 59 J/(K mol) with a n gible volume change]. Since typical alkali thiocyanate entropies of fusion are 30-40 J/(K mol) it is reasonable to assume that the high-temperature crystal state is that of a condis crystals with considerable conformational freedom.

Alkyl thiocyanates, R—S—C=N, of lower carbon numbers are highly toxic. These compounds liberate HCN as a result of metabolic processes and can cause death (Manahan 1989). Methyl thiocyanate [556-64-9] is highly toxic, with an intravenous LD50 value of 18 mg/kg in mice (NIOSH 1986). Ethyl thiocyanate [542-90-5], allyl thiocyanate [764-49-8], butyl thiocyanate [628-83-1], and amyl thiocyanate [32446-40-5] are all toxic compounds with an LD50 (subcutaneous) value of less than 100 mg/kg. The phenyl ester [5285-87-0] exhibits greater toxicity (intravenous LD50 value in mice 6.7 mg/kg) than that of the aliphatic esters of thiocyanic acid. [Pg.873]

The 10-mlnute Co82 produced by the Ni82(n,p) reaction has been extracted as the thiocyanate into an organic layer of amyl alcohol-ethyl ether (l l) from a weak hydrochloric acid solution saturated with ammonium thiocyanate and then back-extracted with 6 N ammonia solution (156,208). The 5-2-minute W17 produced by a Ta (p,3n) reaction has also been extracted as the thiocyanate of W(lV) Into ethyl acetate (268). [Pg.36]
