Bicomponent catalysts and methods for making bio-based acrylic acid, acrylic acid derivatives, or mixtures thereof from lactic acid, lactic acid derivatives, or mixtures thereof are provided.

Bi-component catalyst and method for dehydrating lactic acid to acrylic acid

Methods for catalytically dehydrating lactate salt to acrylic acid, acrylate salt, or mixtures thereof with high yield and selectivity and without significant conversion to undesired side products, such as, acetaldehyde, propionic acid, and acetic acid, are provided. The catalysts include acid-base bifunctional catalysts.

Method for the dehydration of lactate salt to acrylic acid or acrylic salt

A method of making terephthalic acid via reductive coupling of two molecules of propiolic acid or propiolic acid derivatives is presented. The reductive coupling can be catalyzed by compounds comprising metals, and propiolic acid or propiolic acid derivatives can be produced from acetylene and carbon dioxide. At least 4 of the 8 carbons in the terephthalic acid are non-fossil-derived.

Production of terephthalic acid via reductive coupling of propiolic acid or propiolic acid derivatives

Disclosed herein are flexible barrier packages composed of materials that are substantially free of virgin, petroleum-based compounds. The flexible barrier packages contain a sealant that has a biobased content of at least about 85%. The sealant is laminated to an outer substrate that has a biobased content of at least about 95% via a tie layer that can further include an extruded substrate. The extruded substrate has a biobased content of at least about 85%. Ink optionally can be deposited on either side of the outer substrate, and the exterior surface of the outer substrate can further include a lacquer. A barrier material layer can be deposited or laminated between the first tie layer and the outer substrate. The flexible barrier packages of the invention are useful for enclosing a consumer product, for example, food, drink, wipes, shampoo, conditioner, skin lotion, shave lotion, liquid soap, bar soap, toothpaste, and detergent.

Flexible barrier packaging derived from renewable resources

Polyphosphonic acid ester compounds with flavorant, coolant and/or sweetener components, and tartar, plaque and/or calculus control compositions with improved taste comprising one or more polyphosphonic acid ester compounds are described.
