Source text - English Encapsulation of heptanoic acid:
Heptanoic acid has been encapsulated in melamine-formaldehyde (MF) shells to produce an emulsion containing approximately 30% of capsules; the heptanoic acid content of the capsules is +/-70% as measured by thermogravimetric analysis (TGA) and by titration of a diluted solution of the capsules with standard NaOH solution.
The use of a polymeric surfactant enhances encapsulation of the partially soluble heptanoic acid. A number of polymeric surfactants were evaluated before poly(styrene-maleic anhydride) (PSMA) was chosen. PSMA must first be solubilised by neutralisation with sufficient NaOH to ensure complete dissolution.
The first step is to begin formation of a MF pre-polymer, by mixing Cymel 285 (a MF resin) with Floset 150L (a polyacrylamide) with PSMA solution and adjusting to pH 5.3 (with acetic acid) and heating to 25°C for a period.
Hepatanoic acid is then added and the mixture emulsified under high shear to create emulsion droplets of a suitable size (generally

Het heptaanzuur is ingekapseld in melamine-formaldehyde (MF) omhulsels om een emulsie te produceren die ongeveer 30% capsules bevat; het heptaanzuurgehalte van de capsules is +/- 70% zoals gemeten door thermo-gravimetrische analyse (TGA) en door titratie van een verdunde oplossing van de capsules met standaard NaOH-oplossing.
Het gebruik van een polymere oppervlakte-actieve stof, verbetert de inkapseling van het gedeeltelijk oplosbare heptaanzuur. Een aantal polymere oppervlakte-actieve stoffen werden beoordeeld voordat poly (styreen-maleïnezuuranhydride) (PSMA) werd gekozen. PSMA moet eerst worden opgelost door neutralisatie met voldoende NaOH om volledige oplossing te verzekeren.
De eerste stap is te starten met de vorming van een MF-pre-polymeer; door Cymel 285 (een MF-hars) te mengen met Floset 150L (een polyacrylamide) met PSMA-oplossing en deze naar pH 5,3 (met azijnzuur) aan te passen en voor een tijdje te verwarmen tot 25° C.
Vervolgens wordt heptaanzuur toegevoegd en wordt het mengsel onder hoge afschuiving geëmulgeerd, om emulsie druppeltjes van een geschikte grootte te creëren (in het algemeen
