چکیده
“I am indebted to Dr. (now Professor Sir Robert) Williams for bringing me into the team [The (British) PHLS Committee on Formaldehyde Disinfection] which investigated the use of formaldehyde for disinfecting fabrics. He gave me the job of finding a nontoxic neutralizing agent with which to treat infected fabric after exposure to formaldehyde vapour, in order that the bacterial viability results should not be invalidated by any bacteriostatic action of residual formaldehyde. “In the course of this work, which had a fairly successful conclusion, I tested various single compounds and then went on to test twocomponent mixtures as suggested by a study of Robinson’s classical researches into alkaloid synthesis in plants, where formaldehyde is a key intermediate.

Nano Al2O3/KF using for synthesis of some Hantzsch type-products
A protocol for the synthesis of 1,4-dihydropyridines (Hantzsch type-products) was developed by means of a three-component condensation of an aldehyde, a β-dicarbonyl compound, ammonium acetate and nano Al2O3/KF as catalyst. This reaction was carried out under different conditions including i) solvent-free ii) and reflux in different solvents. In all conditions, the desired products were obtaine...

A facile, ultrasensitive, and selective sensor strip utilizing 4-amino-3-penten-2-one (fluoral-p) functionalized electrospun polyacrylonitrile (PAN) (PAN/fluoral-p) nanofibrous membranes has been successfully developed for naked-eye colorimetric assay of formaldehyde. The sensor strips presented a significant reflectance decreasing band at 417 nm which induced a vivid color change from white to...
