- Almond meal is commercially available from the Sigma Chemical Company. The material used in the experiments described here was prepared by grinding almonds and defatting three times with ethyl acetate
- To avoid the use of free HCN and to saturate ethyl acetate with an acetate buffer pH = 5.5 the following procedure was followed: NaCN (2.1 g, 43 mmol) was dissolved in water (75 mL). Acetic acid was added until pH = 5.5. The HCN was then extracted with ethyl acetate (75 mL). The amount of HCN in the organic phase was determined by a slightly modified literature procedure14; 1.0 mL of the organic phase was diluted with 20 mL of water and 5 mL of a whirling Mg(OH)2 suspension in water and titrated with 0.1 N AgNO3 using K2CrO4 as indicator.
