Description
Гексахлорбутадиен CCl2 CCl-CCl CCl2 взрывобезопасен, не горюч , инертен к металлам, имеет относительно невысокую испариваемость . Ввиду этих качеств гексахлорбутадиен предлагаетс в р де патентов как гидравлическа жидкость, в том числе в различных устройствах самолетов и ракетной техники. Однако поскольку температура замерзани гексахлорбутадиена равна всего лишь минус 21°, его применение дл указанной цели без специальных добавок, понижающих температуру замерзани оказываетс невозможным.Hexachlorobutadiene CCl2 CCl-CCl CCl2 is explosion-proof, non-flammable, inert to metals, has a relatively low evaporability. In view of these qualities, hexachlorobutadiene is proposed in a number of patents as a hydraulic fluid, including in various devices of airplanes and rocket technology. However, since the freezing point of hexachlorobutadiene is only minus 21 °, its use for this purpose without special additives that lower the freezing point is not possible.
В св зи с этим большой интерес представл ет подбор присадок, которые по основным свойствам не отличаютс от гексахлорбутадиена и, таким образом, не измен ют его положительных сторон как гидравлической жидкости.In this connection, it is of great interest to choose additives that, due to their basic properties, do not differ from hexachlorobutadiene and, thus, do not change its positive sides as a hydraulic fluid.
В цел х снижени температуры застывани гидравлической жидкости гексахлорбутадиена, предлагаетс примен ть в качестве присадки гексахлОр пропилен.In order to lower the pour point of the hydraulic fluid of hexachlorobutadiene, it is proposed to use hexachloropropylene as an additive.
В приведенных примерах показано, как измен етс температура застывани гексах.чорбутадиена в зависимости от количества введенного в него гексахлорпропилена.The examples given show how the pour point of hexach.chorbutadiene varies depending on the amount of hexachloropropylene introduced into it.
Знак 76 показывает, что практически температура значительно ниже -76.Sign 76 indicates that in practice the temperature is well below -76.
Предмет изобретени Subject invention
Способ понижени температуры замерзани гексахлорбутадиена - компонента гидравлической жидкости, отличаюш,ийс тем, что в гексахлорбутадиен ввод т гексахлорпропилен.The method of lowering the freezing temperature of hexachlorobutadiene, a component of hydraulic fluid, is distinguished by the fact that hexachloropropylene is introduced into hexachlorobutadiene.
