Capryl alcohol.

Beckmann rearrangement of cvc7ohexanone oxime. M.p. 68-70 C, b.p. I39 C/12 mm. On healing it gives polyamides. Used in the manufacture of Nylon[6]. Cyclohexanone oxime is formed from cyclohexane and niirosyl chloride. U.S. production 1978 410 000 tonnes, capryl alcohol See 2-octanol. caiH Uc acid See oclanoic acid.

Alkali Fusion. Tha alkaU fusion of castor oil using sodium or potassium hydroxide in the presence of catalysts to spHt the ricinoleate molecule, results in two different products depending on reaction conditions (37,38). At lower (180—200°C) reaction temperatures using one mole of alkah, methylhexyl ketone and 10-hydroxydecanoic acid are prepared. The 10-hydroxydecanoic acid is formed in good yield when either castor oil or methyl ricinoleate [141-24-2] is fused in the presence of a high boiling unhindered primary or secondary alcohol such as 1- or 2-octanol. An increase to two moles of alkali/mole ricinoleate and a temperature of 250—275°C produces capryl alcohol [123-96-6] CgH gO, and sebacic acid [111-20-6] C QH gO, (39—41). Sebacic acid is used in the manufacture of nylon-6,10.

Capryl System (I), Reversed Phase. The paper is impregnated with capryl alcohol, and aqueous 0.2Af phosphate buffer at pH 6.5 is used as developing solvent. 

Partition Column. Two columns packed with coarse powdered cellulose impregnated with capryl alcohol as immobile phase were prepared in an identical manner. The mobile phase consists of 0.2Af phosphate buffer at pH 6.5. To avoid overloading the column, only a small portion of the extract could be used. The natural extract consisted of 0.20 ml. of the reduced-pressure evaporated solution, corresponding to about 10 grams of kudzu. A similar quantity was added as the spiked extract, except that it contained 500 /xg. of added GA3. Ten-milliliter eluent fractions were collected, acidified to pH 2, and extracted with ethyl acetate. The ethyl acetate extracts were concentrated prior to chromatography.

During the early forties flexible PVC use was mainly limited to military applications, including wire and cable, and various film and sheeting applications, etc. With the conclusion of World War II, new markets for PVC developed rapidly. Aside from DOP, which was commercialized in 1940(4), dicapryl phthalate (DCP) was introduced by Rohm and Haas C5), also in the early forties. With the development of plastisols(6), DCP became a plasticizer of choice because of the favorable balance of properties it imparted — especially low viscosity. However, DCP s subsequent growth has been limited since capryl alcohol (octanol-2), a monohydric secondary alcohol, is a by-product of limited volume sebacic acid manufacture. 

It is noteworthy that the only monohydric secondary alcohols that have found any use in PVC plasticizers are capryl alcohol (octanol-2) and cyclohexanol. No tertiary alcohols have found use at all, probably because of the difficulty of esterification, at least.
