摘要： The present invention relates to a stabilized plant protecting agent suspension which can be characterized by containing 10 to 60% by weight of one or more active ingredients, 30 to 5% by weight of oily layer, 0 to 10% by weight of emulsifier, 10 to 20% by weight of conventionally used excipient and water needed to 100% by weight while by increasing solid concentration oil concentration decreases. The invention also provides a process for the preparation of a stabilized plant protecting agent suspension by adding oil and optionally an emulsifier and/or water containing layer to a suspension of a suitable particle size of the active ingredient and water soluble excipients, such as surfactants, optionally emulsifiers, dispersing agents, viscosity modifying agents, protective colloids and mixing together the suspension layer and the layer containing the oil with a stirrer of great shearing force and optionally adding to the obtained stabilized suspension further excipients, e.g. viscosity modifying agents, anti-foaming agent, protective colloid and dispersing agent.
摘要翻译：本发明涉及稳定的植物保护剂悬浮液，其特征在于含有10至60重量％的一种或多种活性成分，30至5重量％的油层，0至10重量％的乳化剂，10 至20重量％的常规使用的赋形剂和水需要100重量％，同时通过提高固体浓度油浓度降低。本发明还提供了一种制备稳定的植物保护剂悬浮液的方法，其通过将油和任选的乳化剂和/或含水层加入到适合的粒度的活性成分和水溶性赋形剂如表面活性剂的悬浮液中，任选的乳化剂，分散剂，粘度调节剂，保护胶体，并将悬浮液层和含有油的层与具有大剪切力的搅拌器混合在一起，并任选地将所得稳定悬浮液中的其它赋形剂粘度调节剂，消泡剂，保护胶体和分散剂。

摘要： The invention relates to a new process for the preparation of stable aqueous suspensions of methyl N-(2-benzimidazolyl)carbamate. According to the invention an aqueous solution of an addition salt of methyl N-(2-benzimidazolyl)carbamate and an inorganic acid, optionally containing an excess amount of acid is reacted with an aqueous potassium, sodium or ammonium hydroxide solution or ammonia gas, in the presence of a wetting, dispersing and antifoaming agent and optionally of a protecting colloid at a temperature of 50.degree. C. to 100.degree. C., and if desired, the suspension obtained is concentrated or diluted. The suspension prepared by this process can either be used directly or can be supplemented with further additive(s) conventionally used in the preparation of plant protecting agents.
摘要翻译：本发明涉及制备N-（2-苯并咪唑基）氨基甲酸甲酯稳定的水性悬浮液的新方法。根据本发明，将N-（2-苯并咪唑基）氨基甲酸甲酯和无机酸的任选含有过量的酸的水溶液与氢氧化钾，氢氧化钠或氢氧化铵水溶液或氨气水溶液反应，在50℃至100℃的温度下存在润湿剂，分散剂和消泡剂以及任选的保护胶体，如果需要，将所得悬浮液浓缩或稀释。通过该方法制备的悬浮液可以直接使用或可以补充常规用于制备植物保护剂的另外的添加剂。
