Batch reactors are the very fundamental process units used for the preparation of a vast majority of chemical raw materials, polymers, additives, intermediates, surfactants used in all sectors of industry. Examples are: paint & coatings, adhesives & sealants, construction chemicals, textile, cosmetics, pharma, personal care, etc.
A batch reactor is a much more sophisticated process machine compared to an agitated vessel or a mixers. It consists of a equipment where specific chemical transformations (syntheses) occur in a controlled way.

Polyethoxylation and polypropoxylation are necessary to prepare nonionic surfactants and many other types of products. The starter (ROH) in the synthesis of a nonionic surfactant could be: a fatty alcohol, an alkylphenol, or a fatty acid, i.e., a hydrophobic molecule containing a polar group with an active hydrogen. Ethoxylation and/or propoxylation reaction are carried out in industry in (a) gas-liquid stirred batch reactor SBR, (b) venturi loop reactor VLR, (c) spray tower loop reactor STLR.

Many industrial chemical processes involve exothermic (heat generating) reactions.
Uncontrolled or runaway reactions can occur as a result of various situations, such as mischarged raw materials, failure of a reactor's cooling system, control systems, or the presence of contaminants. If the heat generation exceeds the reactor's ability to remove it, the reaction can accelerate - or run away - and cause the temperature and pressure to increase. A sudden energy release from such an uncontrolled reaction has the potential to harm workers, the public, and the environment. Selection of CSB's investigations - VIDEOS [.....]
Though often confused, agitation, mixing, dispersion are not synonymous. Agitation refers to the induced motion of a material in a specified way, usually in a circulatory pattern inside a vessel. Mixing is the random distribution, into and through one another, of two or more initially separate phases. Dispersion is when solid particles are merely suspended in a liquid..[.....]

Adhesives & sealants are products where polyurethane has been successfully used since decades, and will certainly be used for the next decades to come. I this sector, an import role is played by one-component moisture curing PU (1CPU). In this article we will try to present a synthetic market landscape, and future trends, of 1CPU adhesive sealants in China and Thailand, specifically for Automotive and Construction applications.

For many years, the concepts of sustainable development and sustainability have been the exclusive territory of the Western richest countries, such as Europe and North America. Only those so-called developed countries were able to develop business under a new spot light, "the green light". Although the vast majority of directives, restrictions, standards and regulations concerning the use of solvents, of biocides and other substances considered harmful to humans and the environment are mainly European and American based, nonetheless they are having a significant impact on Southeast Asia countries.

Solvents are liquids that have the property to dissolve and keep in suspension the basic materials that constitute a paints, such as main polymers, binders, additives, pigments, without changing their chemical properties. Beside of this important function, solvents present also very aggressive chemical properties, which makes them harmful for humans and wild life. Today new formulations are possible using new species of polymers that utilize water as the main carrier, in additions to very small quantity of co-solvents, as low as 3 - 5 %.

We Asiantech, as designers of chemical plants that may be sometime dangerous, we have always felt within ourselves the responsibility to build ever safe systems that can create new jobs and that can never in any case cause any harm to people and the environment. We are pleased to report the message from Vanessa Allen Sutherland, Chairman of the Chemical Safety Board. [....]
