Nonyl aldehydes

Nonyl aldehyde (32.66 g, 0.23 mol) and furan (200 mL, 187.2 g, 2.75 mol) were mixed in a 250-mL photolysis flask equipped with a quartz immersion well containing a Vycor filter and a 450-W Hanovia Lamp. The system was kept at -20° C with an isopropyl alcohol bath cooled by a Cryocool Immersion Cooler (CClOO). Nitrogen was bubbled throughout the duration of the reaction, and the solution was stirred vigorously. Additional furan (150 mL, 140.4 g, 2.06 mol) was added during the course of the reaction. TLC analysis indicated completion of the reaction after 20 h. After evaporation of excess furan and NMR analysis of the resultant oil (48.70 g, ca. 100%) indicated the desired photoadduct had been formed, without contamination from unreacted nonyl aldehyde.

Figure 34 shows the results for alcohol (methanol, ethanol, 1-propanol and 1-butanol), ketone (acetone and diacetyl), terpene (pinene and linalool), aldehyde (n-nonyl aldehyde) and ester (acetic acid n-amyl ester and n-butyric acid ethyl ester) of various concentrations. Because of the linear characteristics of the CTL-based sensor, the plots are located in a similar region for a certain type of gas of various concentrations where the Henry-type adsorption isotherm holds. Thus, we can identify these gases with various concentrations by simple data-processing.

Since 1951, the ozonolysis of oleic acid (I) from sperm oil has been studied in this laboratory good yields of nonyl aldehyde (II), nonanoic acid (III), and azelaic acid (V) have been obtained. 

The nonyl aldehyde coproduct of the azelaic half aldehyde is a useful intermediate after being transformed into the corresponding alcohol, acid, or amine, it is a raw material for plastics. Several years ago, I. Sakurada, Kyoto University, the inventor of Vinylon, found that when nonyl aldehyde is used instead of formalin for acetalization of poly (vinyl alcohol), the properties of Vinylon yarns are considerably improved, especially in elastic recovery. 

Derivation By the oxidation of nonyl alcohol or nonyl aldehyde by the oxidation of oleic acid, especially by ozone.

The principal constituents of the oil are limonene and citral, together with small quantities of pinene, phellandrene, octyl and nonyl aldehydes, citronellal, geraniol, geranyl acetate, and the stearopten, citraptene. 

A large number of constituents have been isolated from otto of rose, many of which are, however, only present in very small quantities. The most important are geraniol, citronellol, phenyl ethyl alcohol, together with nerol, linalol, citral, nonylic aldehyde, eugenol, a sesquiterpene alcohol, and the paraffin stearopten. 

They agree with Schorger that the principal constituent of the oil is heptane. They do not agree, however, that citronellal is present, but. have identified decylic acid possibly traces also of octylic and nonylic aldehydes may be present. Linalol and methyl-chavicol are also probably present. 

Schimmel Oo. have isolated from the oil furfurol a terpene which was not identified (specific gravity 0 861 rotation h- 10 40 ) decyl aldeyde nonyl aldehyde naphthalene (a very rare constituent of essential oils) and a ketone of the formula OjoH igO. They do not agree with Tiemann and Kruger that oleic aldehyde is present in the oil. 

Dodge has isolated a small quantity of an aldehyde, which appears to be decyl aldehyde. Brooks has identified methyl-heptenone, nonyl aldehyde, linalol, acetic and caprylic esters, a phenol (chavicol ), and a -sesqmterpene alcohol having the characteristic odour of the oil. This body C Hj,0, which has been termed zingiberol, boils at 154 to 157 at 14 5 mm. pressure.
