  • Reduced odor esters and process for producing same
    Patent number: 6635775
    Abstract: An improved process for preparing reduced-odor or odorless esters, preferably benzoate esters, octanoate esters, aliphatic emollient esters and glycol dibenzoate esters. The improved process comprises, in part, removing the esterification catalyst from the crude ester after the esterification reaction is substantially complete, before neutralization of acidity. The resultant ester compositions are odorless or have substantially reduced odor as compared to commercially available esters.

  • Preparation of high purity neem seed extracts
    Patent number: 5420318
    Abstract: A new process has been developed for preparing high purity neem seed extract by adsorbing aqueous solutions of neem seed extract containing azadirachtin onto a macroporous polymeric adsorbent followed by desorption using a solvent. The resulting extract, optionally formulated, is a useful insecticide for the control of foliar pests.

  • Purification of fluorinated carboxylic acids
    Patent number: 5312935
    Abstract: Fluorinated carboxylic acids which do not have the required purity for use as emulsifier in the polymerization of fluorinated monomers can, if necessary after prior de-watering, be treated with oxidants, whereupon the isolation of the pure product is carried out by crystallisation or, preferably, by distillation.

  • Process for the production of stable ozonized oils from unsaturated vegetable oils
    Patent number: 5183911
    Abstract: Production of stable ozonized oils from unsaturated vegetable oils by introducing an ozone-oxygen mixture into the oil until it reaches saturation, and following the ozonization, an extraction process in acid medium is carried out in the presence of a redox reaction system, which is capable of moderately reacting the radicals in the presence of a synthetic or natural anti-oxidation medium or reducing medium.
