Investigation of cold colored smoke production / by T. Liberman.: DR52-9/7-1985E-PDF

"Different methods for producing large colored smoke clouds for use as spotting charges are evaluated. The problem of the disappearance, or "bleaching", of the orange color from vanadium oxytrichloride (VOCl3) clouds during times of high relative humidity is considered. It is postulated that this is caused by the absorption of large quantities of atmospheric moisture by the smoke. A model has been developed to study the process. This model makes the key predictions concerning the absorption of very large amounts of atmospheric moisture by VOC3-type smokes above a relative humidity of 80% and the very small importance of temperature as a parameter. These predictions are, in general, corroborated very well by experiment. Possible solutions to this color bleaching problem are discussed, including one that calls for the synthesis of hydrolyzable vanadium compounds with nonhydroscopic leaving groups."--abstract (page i).
