Procedure: To a 50-mL conical bottom plastic vial was added methyl laurate (38.5 mmol), dimethylaminobutanol (46.2 mmol, 1.2 eq), and Novozym 435 (400 mg). A syringe was inserted through the cap and two additional holes were punched for gas to exit. Nitrogen was bubbled at a rate sufficient to mix the contents. The vial was placed in a heating block set to 65° C. The reaction was monitored by GC/MS to observe the disappearance of starting material. The reaction was complete after approximately 24 hours. The reaction mixture was allowed to cool. The Novozym 435 was removed by filtration to afford the product as a pale, yellow oil (9.2 g; 67% yield) without further purification.

Procedure: After 469 g of a 70% by weight sorbitan aqueous solution (aldehyde value of sorbitan: 6.5 ppm) and 556 g of methyl laurate were charged into a 2000 mL four-neck flask fitted with a stirring apparatus, a thermometer, and a nitrogen gas inlet, dehydration was performed at 110° C. under a nitrogen stream at normal pressure for 1 hour and further at 110° C. under a nitrogen stream at 4 kPa for 1 hour. The whole was cooled to 65° C. and, after 35.4 g of a 5% by weight sodium methoxide methanol solution and 0.44 g of sodium hypophosphite were added thereto, was heated under a nitrogen stream at normal pressure to 150° C. as a reaction temperature. After the temperature reached 150° C., the reaction was carried out under a nitrogen stream at normal pressure. At the time point when the spot of methyl laurate as a raw material disappeared on thin-layer chromatography, it was judged that the reaction was completed. The reaction time was 8 hours and, after the completion of the reaction was confirmed, the product was filtrated at 80° C. to obtain sorbitan monolaurate. fitted with a stirring apparatus was performed at 110° C. under a nitrogen for 1 hour was heated under a nitrogen stream at normal pressure to 150° C. as a reaction temperature reached 150° C. The reaction time was 8 hours the product was filtrated at 80° C.

Procedure: In a first stage to a reactor, equipped with a distillation column, condenser, and graduated receiver, 199.8 g (1.5 mol) of diisopropanol amine (DIPA) and 7.5 g of CH3ONa (30% in methanol) were added and the batch heated to 75° C. 160.5 g (0.75 mol) of methyl laurate were added during 2 hours at 75° C. Temperature was gradually increased during 3 hours. Methanol has been removed at lower pressure 26,660 Pa) and at 120° C. and excess of DIPA has been removed at a pressure below 133 Pa and at 140° C. The so prepared amide looked as yellow fat (melting temperature of above 130° C). In a second stage 0.5 weight % of zinc acetate, based on the intermediate product after stage 1 were added and the batch was heated at 180° C. for 6 hours. Fraction distillation has been done at a pressure below 133 Pa. Three fractions were obtained: I) with boiling point <105° C.; amount above 5 weight %; mainly DIPA; II) with boiling point 105-145° C.; amount 50 weight %; amide acetal (purity 90%) and III) 45 weight %—distillation rest. The yield of amide acetal calculated on methyl laurate was 43%. Initial color and color stability during storage (on shelf) of an amide acetal prepared according to the invention and a comparative amide acetal prepared from nitriles have been evaluated. The amide acetal according to the invention shows a better initial color and better color stability than the amide acetal prepared from nitrites. In a first stage to a reactor, equipped with a distillation column, condenser were added Temperature was gradually increased during 3 hours Methanol has been removed at lower pressure 26,660 Pa) and at 120° C. excess of DIPA has been removed at a pressure below 133 Pa and at 140° C The so prepared amide were added the batch was heated at 180° C. for 6 hours Fraction distillation Three fractions were obtained amide acetal (purity 90%) and III) 45 weight %—distillation rest Initial color and color stability during storage (on shelf) of an amide acetal prepared

Procedure: To a 1 liter stirred reactor, equipped with a distillation column, condenser, and graduated receiver, the following constituents were added: 261.2 g of diisopropanol amine (DIPA) and 432.0 g (98%) of methyl laurate. The contents were heated slowly to 230° C. under a nitrogen blanket. After 5.5 hours, 57 ml of methanol (0.72 equivalent) had come overhead. The pressure was then slowly lowered to strip out unreacted DIPA. At a batch temperature of 180° C. and a pressure of 293 Pa, a cut consisting of 79.7 g of DIPA and 87.8 g of methyl laurate was removed. The batch temperature was then raised to 200° C. and the pressure dropped to 267 Pa. During this period, a cut of 140.9 g of the amide acetal was recovered. This represents a 35.7% conversion of the methyl laurate to amide acetal. equipped with a distillation column, condenser the following constituents were added At a batch temperature of 180° C. was removed The batch temperature was then raised to 200° C. the pressure dropped to 267 Pa During this period a cut of 140.9 g of the amide acetal was recovered

Procedure: Fermentation of dodecane with strain H534 under the standard fermentation conditions (Example 20) produced approximately 139 g/l within 233 hrs with a substrate conversion efficiency of 32.1%. The final production rate was 0.58 g/l/hr. The product was 82.7% dodecanedioic acid. The remaining product was predominantly adipic acid. With methyl laurate as the substrate, H534 produced 115.3 g/l dicarboxylic acid within 223 hrs with a substrate conversion efficiency of 34.6%. The production rate was 0.49 g/l/hr. The product was 89.1% dodecanedioic acid. The remaining product was predominantly adipic acid.
