Description
Известно применение инсектицидов , в том числе и ДДТ, в смеси с минеральными маслами или хлорбензолом .The use of insecticides, including DDT, in a mixture with mineral oils or chlorobenzene is known.
Использование ДДТ и гексахлорциклогексана в сельском хоз йстве СССР ограничивалось, а эффективность Применени снижалась вследствие невозможности производить влажную обработку водными эмульси ми . Прюизводственное изготовление эмульсин бЫло затруднено отсутствием или дефицитностью р да ингредиентов, вход щих в состав рецептур.The use of DDT and hexachlorocyclohexane in the USSR agriculture was limited, and the effectiveness of the Application decreased due to the inability to produce a wet treatment with water emulsions. The production of emulsin was hampered by the absence or deficiency of a number of ingredients included in the recipes.
Преимуществом описываемого способа изготовлени концен.трированных водных эмульсий ДДТ и гексахлорциклогексана вл етс возможность получени их на основе до-ступного и дещевого эмульгатора, улучшающего стойкость эмульсии и повыщающего концентрацию действующего начала.The advantage of the described method of making concentrated aqueous emulsions of DDT and hexachlorocyclohexane is the possibility of obtaining them on the basis of an available and batch emulsifier that improves the stability of the emulsion and increases the concentration of the active principle.
Предлагаемый способ отличаетс The proposed method is different.
от известных тем, что в качествеfrom famous in that as
эмульгатора примен ют сульфитный emulsifier used sulfite
щелок, а в качестве инсектицидаliquor and as an insecticide
примен ют .смесь изомеров гексахлорциклогексана . С целью лобыщени концентрации действующего начала и увеличени стойкости эмульсии , примен ют смесь изомеров гексахлорциклогексана , содержащуюне менее 23% гамма-изомера.a mixture of hexachlorocyclohexane isomers is used. In order to isolate the concentration of the active principle and increase the stability of the emulsion, a mixture of isomers of hexachlorocyclohexane containing not less than 23% of the gamma isomer is used.
Изготовление концентрированных водных эмульсий ДДТ и гексахлорциклогексана осуществл ют следую.щим образом.The manufacture of concentrated aqueous emulsions of DDT and hexachlorocyclohexane is carried out as follows.
В качестве эмульгатора-стабилизатора примен ют технически дост т1ный сульфитный щелок (сульфитно-целлюлозна барда). В состав эмульсий вход т: трансформаторное или веретенное масло (в качестве масл ной фазы может ;:быть использовано такжедизельное топливо и сол ровое масло) в количестве 40%; ДДТ или гексахлорциклогексан (содержащий до 25-27% гамма-изомера) -20%; сульфитный щелок (в пересчете на сухое вещество) -6% и 34% воды.Technically available sulphite liquor (sulphite-cellulose stillage) is used as an emulsifier-stabilizer. The composition of the emulsions includes: transformer or spun oil (as an oil phase;: diesel fuel and salt oil can also be used) in an amount of 40%; DDT or hexachlorocyclohexane (containing up to 25-27% of gamma isomer) -20%; sulfite liquor (in terms of dry substance) -6% and 34% water.
Способ пригртовлен-и состоит в том, что ДДТ или обогащенный гамма-изомером гексахлорцйклогексан раствор ют в одном из указанных выще минеральных масел приThe method is prigruvlen - and consists in the fact that DDT or hexachloro-cyclohexane enriched with gamma isomer is dissolved in one of the above mineral oils with
