• separation
  • It is also possible to obtain separation of a few parts per million of a contaminant from a mixture of much more concentrated materials. (encyclopedia.com)
  • The batch process most often consists of introducing accurately measured amounts of starting materials into a vessel followed by a series of processes involving mixing, heating, cooling, making more chemical reactions, distillation, crystallization, separation, drying, packaging etc., taking place at predetermined and scheduled intervals. (wikipedia.org)
  • methyl
  • When methanol and carbon monoxide are combined in the presence of a strong base, the result is methyl formate, according to the chemical equation: CH3OH + CO → HCO2CH3 In industry, this reaction is performed in the liquid phase at elevated pressure. (wikipedia.org)
  • typically
  • Because individuals typically have different levels of response to the same dose of a toxic substance, a population-level measure of toxicity is often used which relates the probabilities of an outcome for a given individual in a population. (wikipedia.org)
  • materials
  • Speciality chemicals are materials used on the basis of their performance or function. (wikipedia.org)
  • In contrast to the production of commodity chemicals that are usually made on large scale single product manufacturing units to achieve economies of scale, specialty manufacturing units are required to be flexible because the products, raw materials, processes &, operating conditions and equipment mix may change on a regular basis to respond to the needs of customers. (wikipedia.org)
  • possible
  • Or, a newly synthesized and previously unstudied chemical that is believed to be very similar in effect to another compound could be assigned an additional protection factor of 10 to account for possible differences in effects that are probably much smaller. (wikipedia.org)
  • water
  • In one of these processes (used by BASF) the formic acid is removed from the water by liquid-liquid extraction with an organic base. (wikipedia.org)
  • family
  • By extension, the word may be metaphorically used to describe toxic effects on larger and more complex groups, such as the family unit or society at large. (wikipedia.org)
  • process
  • A process for chemically bonding an odor-encapsulating agent to textiles includes reacting a cyclodextrin with a cross-linking agent capable of forming ether bonds with the cyclodextrin and with the textile material, and curing the textile material treated with a mixture of the cyclodextrin and cross-linking. (google.com)
  • 7. The process of claim 6 , wherein the compound complexed with the cyclodextrin comprises an antimicrobial agent, a perfume, an odor-mitigating chemical, or an insecticide. (google.com)
