  • 1 Introduction: Green Chemistry and Catalysis

    green process for its production. Green chemistry eliminates waste at source, i.e. it is primary pollution prevention rather than waste remediation (end of pipe higher since the yield is not 100% and an excess of reagent(s) is used and sol vent losses and salt generation during work up have to be taken into account.

  • Kraft process

    The kraft process (also known as kraft pulping or sulfate process) is a process for conversion of wood into wood pulp, which consists of almost pure cellulose fibers, the main component of paper.The kraft process entails treatment of wood chips with a hot mixture of water, sodium hydroxide (NaOH), and sodium sulfide (Na 2 S), known as white liquor, that breaks the bonds that link lignin

  • Precipitation (chemistry)

    An important stage of the precipitation process is the onset of nucleation. The creation of a hypothetical solid particle includes the formation of an interface, which requires some energy based on the relative surface energy of the solid and the solution. If this energy is not available, and no suitable nucleation surface is available

  • Blue White Select Screening Reagent Sigma Aldrich

    Add 40 µl of the Blue White Select Screening Reagent to the top agar medium. Notes: If desired, the Blue White Select Screening Reagent may be stored as a DMSO/water solution at 20 °C. The DMSO must be 8085% (v/v) of the solution. Take a portion of the stock solution and add sufficient water to make up 1520% of the volume.

  • Lawesson's Reagent organic chemistry

    Lawesson's Reagent. Lawesson's Reagent is a mild and convenient thionating agent for ketones, esters, and amides that allows the preparation of thioketones, thioesters and thioamides in good yields. Reactions using the comparable reagent P 4 S 10 normally need higher temperatures and a large excess of the thionating agent.
