Description
Известен способ получени красного фосфора полимеризацией л елтого фосфора с перемешиванием и наружным обогревом, а также пр 1мепепие дл получени красного фосфора двух последовательно соединенных шнеков.A known method for the production of red phosphorus is the polymerization of yellow phosphorus with agitation and external heating, as well as the pattern for the production of red phosphorus of two serially connected augers.
Предложенный непрерывный ретурный способ получени красного фосфора заключаетс в том, что смесь желтого фосфора с красным фосфором , вз тых в соотношении от 1 : 4 до 1 : 7 подвергают полимеризации с применением наружного обогрева в двух и более наклонных шнеках, соединенных последовательно, с возвращением заданной части образовавшегос красного фосфора из последнего шнека в первый на смешение с желтым фосфором.The proposed continuous retour process for producing red phosphorus is that a mixture of yellow phosphorus with red phosphorus, taken in a ratio of from 1: 4 to 1: 7, is polymerized using external heating in two or more inclined augers connected in series with the return portions of the red phosphorus formed from the last screw into the first one for mixing with the yellow phosphorus.
Отличительной особенностью предложенного способа от известного вл етс то, что иолимеризации подвергают смесь желтого фосфора с красным фосфором в соотношении от 1 :4 до 1:7.A distinctive feature of the proposed method from the known one is that a mixture of yellow phosphorus with red phosphorus in a ratio from 1: 4 to 1: 7 is subjected to polymerization.
Преимушество предложенного способа заключаетс в том, что присутствие красного фосфора в заданном соотношении с желтым фосфором , как показали опыты, создает автокаталитическое ускорение процесса полимеризации желтого фосфора. Через 12 часов в полимере практически не остаетс желтого фосфора, а полученный продукт имеет физическую структуру сыпучего мелкораздробленного порошка, аналогичного исходному красному фосфору.The advantage of the proposed method is that the presence of red phosphorus in a given ratio of yellow phosphorus, as shown by experiments, creates an autocatalytic acceleration of the process of polymerization of yellow phosphorus. After 12 hours, almost no yellow phosphorus remains in the polymer, and the resulting product has the physical structure of a fine finely divided powder similar to the original red phosphorus.
В таблице приведены данные лабораторных исследований о содержании желтого фосфора в полимере в зависимости от характера смеси и времени нолимеризац1:и.The table shows the data of laboratory studies on the content of yellow phosphorus in the polymer, depending on the nature of the mixture and the time nolimerizats1: and.
