- the composition of secondary alcohol alkoxylates exhibits a narrow monomodal weight distribution.
- the weight distribution is determined by analysis by gas chromatography on a standard column and flame ionization detection (FID) well known to those skilled in the art, where the various components of the compositions analyzed are separated by increasing boiling point and therefore by increasing molar mass by addition each time of an alkylene oxide unit.

- the capping reaction carried out on such compositions with wide distribution and significant residual can present difficulties of realization (reaction media which can be viscous making their handling difficult, insufficient yields, and others) and thus lead, in certain cases, to to capped alkoxylate compositions with application properties that are not very acceptable, or even mediocre. This is moreover very probably what explains why until now such capped alkoxylates have not developed industrially at the present time.
- the capped alcohol alkoxylates, and most particularly the capped secondary alcohol alkoxylates, described here have a narrow distribution, and in a very unexpectedly, greatly improved application performance.

- Table 2 Weight distribution 1-decanol 5 EO - The 2s value calculated with the values resulting from the basic catalysis is 7.3, while this 2s value calculated with the values resulting from the DMC catalysis is 3.7.
- 500 g (3.16 M) of bio-sourced 1-decanol (marketed by Ecogreen) are charged, dried at less than 100 ppm of water. and 1.5 g (3000 ppm) of solid KOH.
- the reactor is closed, purged with nitrogen and the pressure tightness is checked.
- the reactor is pressurized with nitrogen.
- the reaction medium is first brought to 90 ° C. with stirring. At a temperature of 120 ° C, 30 g of ethylene oxide are introduced. When the reaction has started, the balance of ethylene oxide, a total of 1807 g (41 M), is introduced over 2 hours and 40 minutes at a temperature of about 140 ° C.
- the temperature is maintained for 30 min and then the residual ethylene oxide is stripped with nitrogen.
- the reactor is cooled to 80 ° C. and 2281 g of 13 EO 1-decanol product are withdrawn. (IOH: 77 mg KOH / g and 480 Hz staining on the molten product).
- the product is a white solid at room temperature.
- the reaction medium is brought to 90 ° C. under bubbling with azde in order to deoxygenate the medium. Nitrogen is then placed in the reactor chamber and then 120 g (3 M) of sodium hydroxide in beads are added.
- the medium is then brought to 100 ° C.-105 ° C. under reduced pressure to approximately 30 kPa so as to distill off the water.
- the stop criterion is a water content of less than 1.5%.
- the reaction medium is then brought to 70 ° C.
- the temperature is maintained for 30 min and then the residual ethylene oxide is stripped with nitrogen.
- the reactor is cooled to 80 ° C. and 2290 g of 13 EO 1-decanol product are withdrawn. (IOH: 75 mg KOH / g and 30 Hz staining on the molten product).
- the product is a white solid at room temperature.
- a nitrogen inerting system 2190 is charged.
- g (3M) of 13 EO 1-decanol obtained previously as well as 10 g of water.
- the reaction medium is brought to 90 ° C. under bubbling with nitrogen in order to deoxygenate the medium.
- Nitrogen is then placed in the reactor chamber and then 132 g (3.3 M) of sodium hydroxide in beads are added.
- the medium is then brought to 100 ° C-105 ° C and under reduced pressure up to about 30 kPa so as to distill the water.
- the stop criterion is a water content of less than 1.5%.
- reaction medium is then brought to 70 ° C., 366 g (2.9 M) of benzyl chloride are added in approximately 60 min. The temperature is maintained for 5 hours at 120 ° C. After returning to 70 ° C., the reaction medium is neutralized with 37% hydrochloric acid until a pH of 7. Water is distilled off under reduced pressure to precipitate the sodium chloride formed. The latter is filtered and 2390 g of 13 EO 1-decanol capped benzyl are recovered.
- the reaction medium is brought to a temperature between 60 ° C and 70 ° C, then 154 g (1.57 M) of maleic anhydride are gradually introduced with stirring while maintaining the temperature. After addition, the temperature is maintained at 70 ° C. for one hour. Then the esterification rate is checked by assay. Then poured, with stirring, 816 g of a 20% aqueous solution of sodium bisulfite (ie 1.57 M) at a temperature between 75 ° C and 90 ° C. After addition, the reaction medium is maiitient at 90 ° C. When the reaction is complete, the reaction medium is cooled, the pH is adjusted by adding sodium hydroxide solution and the reactor is emptied.
- the medium is brought with stirring and an inert atmosphere to 115 ° C. Then the assembly is gradually placed under reduced pressure to a value of 30 mm Hg (ie 4 kPa). The water formed is distilled and collected in a cold trap. The reaction is continued for about 7 hours, so as to convert all of the glucose.
