A new process for acrylic acid synthesis by fermentative process

Abstract

With the synthesis of chemical products through biotechnological processes, it is possible to discover and to explore innumerable routes that can be used to obtain products of high added value. Each route may have particular advantages in obtaining a desired product, compared with others, especially in terms of yield, productivity, easiness to separate the product, economy, and environmental impact. The purpose of this work is the development of a deterministic model for the biochemical synthesis of acrylic acid in order to explore an alternative process. The model is built-up with the tubular reactor equations together with the kinetic representation based on the structured model. The proposed process makes possible to obtain acrylic acid continuously from the sugar cane fermentation.

Dehydration of Lactic Acid: The State of The Art

“…On the basis of the established metabolic routes, bacterial growth models, and a bioethanol production model, the team of Lunelli et al proposes an acrylic acid synthesis process from glucose via pyruvate and lactate. On the other hand, in 2013, Straathof et al noted that processes based on enzyme activity always suffer from parallel fermentation as well as the need for an external electron acceptor.…”

Analysis of Kinetic and Operational Parameters in a Structured Model for Acrylic Acid Production through Experimental Design

“…A deterministic mathematical model for simulating the biotechnological synthesis of acrylic acid was developed in a previous study [3] to explore an alternative process. The proposed process makes it possible to obtain acrylic acid continuously from the sugarcane fermentation.…”

A Green Route to Petroleum Feedstocks: Photochemistry of Fats and Oils

“…The increased demand for sustainable development, together with the ever fluctuating cost of petroleum-based raw materials, makes the development of new processes that provide more economical and greener alternatives to conventional methods in forming base feedstocks for commercial polymers imperative. One approach, the development of the biodiesel industry, generates biofuel from vegetable/animal oil sources. − Another development is that of biobased routes that generate carbon-containing building blocks, some of which may be more conventionally obtained from petroleum derivatives. − …”

“…Independent of the source of fat, irradiation of these triglycerides with deep UV light results in the products of Norrish type II cleavage. − Although extensively studied for ketone systems, to the best of our knowledge, this is the first report that uses this reaction with animal and vegetable fat sources. Product glycerol can be transformed through catalytic processes into acrylic acid and other essential raw materials for the plastic industry. − …”
