IUPAC Name:

Sodium ethasulfate is a clear, colorless, viscous, and nonflammable liquid that belongs to the sodium sulfate chemical group. Sodium ethasulfate is usually stable;
however, it is incompatible with strong oxidizing agents. Due to its unique solubility and penetrating action, it is widely used in various end-user industries such as
 textile, chemical production, pharmaceuticals, agrochemicals, metal working, and food processing. Sodium ethasulfate is used as wetting agent in the textile industry. 
The product is used along with calcium hypochlorite as a bleaching agent. The product is used as mercerizing agent for cotton processing in the chemical industry.
 Sodium ethasulfate is employed as intermediate in anoinic surfactants that are used for dishwashing detergents. It is also used as surfactant in lye washing and peeling process.
 In the pharmaceutical industry, it is used to enhance the bactericidal properties of generic antiseptics that are more acidic. It is also employed as surfactant in penicillin
 production for breaking undesired reaction conditions.

Synthesis
Currently, sulfated reaction through continuous reactor (such as: falling film reactor) is the most widely used method for preparing sulfates.
Generally, 2-ethylhexyl alcohol and sulfur trioxide react through reactor, then sodium hydroxide neutralizes, finally obtain product.
US patent 8,921,588 (Process for preparing sulfates and/or sulfonates in a micro-reaction system) presents a synthetic process. Conditions: mole ratio of sulfur trioxide and alcohols or other raw materials: 1:1; temperature: 30-60°C; reactor: falling film reactor.

US patent 6,060,443 (Mid-chain branched alkyl sulfate surfactants) also presents some synthesis processes of branched chain sulfate.

US patent 6,455,488 (Process of making alkyl sulfate granulates) describes the preparation of a particulate alkyl sulfate, but does not involve the synthesis process.
