Exempel på hur man kan använda PARAFORMALDEHYDE i en mening

• Short-chained POM (chain length between 8 and 100 repeating units) is also better known as paraformaldehyde (PFA).
• Some commonly used fixatives are 4% formaldehyde or paraformaldehyde (PFA) in phosphate buffered saline (PBS).
• The Tishchenko reaction of paraformaldehyde in the presence of aluminum methylate or magnesium methylate forms methyl formate.
• Once paraformaldehyde is depolymerized, the resulting formaldehyde may be used as a fumigant, disinfectant, fungicide, and fixative.
• Salicylaldehydes in general are prepared by ortho-selective formylation reactions from the corresponding phenol, for instance by the Duff reaction, Reimer–Tiemann reaction, or by treatment with paraformaldehyde in the presence of magnesium chloride and a base.
• It is also produced as a byproduct in the Blanc chloromethylation reaction, formed when formaldehyde (the monomer, paraformaldehyde or formalin) and concentrated hydrochloric acid are mixed, and is a known impurity in technical grade chloromethyl methyl ether.
• PODE can be produced from methylal and formaldehyde or a formaldehyde equivalent such as paraformaldehyde or trioxane.
• First off, a Vilsmeier-Haack reagent is prepared by refluxing paraformaldehyde and dimethylamine hydrochloride in isopentanol at a temperature of 131 °C while removing water from the isopentanol using a Dean-Stark separator.
• Adiponitrile and formaldehyde (aqueous, paraformaldehyde, or trioxane) are combined with an acid (typically sulfuric acid) in a reactor.
• Presently, some of the agents used in the fixation process include two variations of formaldehyde (formalin and paraformaldehyde), 70% ethanol, glutaraldehyde and TCA.
• In organic synthesis, the Casiraghi formylation is the formation of a salicylaldehyde from a phenol and paraformaldehyde.
• It can also be prepared by formylation of mesitylene by reacting Mesitylene with a formyl group source such as paraformaldehyde or DMF (N,N-dimethylformamide) under specific conditions with a suitable catalyst.
