      Product Detail  


    Diphosphorus pentoxide is also known as phosphoric anhydride. It is a phosphorus oxide formed when white phosphorus, yellow phosphorus or red phosphorus burns in dry air. At room temperature, it is a white soft powder or colorless monoclinic crystal. It is highly hygroscopic and has a melting point of 580-585℃. Its relative density is 2.39, and it sublimes at 347℃. Under pressure and heated to 563℃, the crystal transforms into an amorphous glassy state (melted). It is insoluble in acetone and ammonia water, but soluble in sulfuric acid. It is prone to absorb moisture in the air and has extremely strong dehydration properties. It can even dehydrate concentrated sulfuric acid to form sulfur trioxide, making it a powerful desiccant. It reacts vigorously with water, releasing heat and white smoke. Each mole of diphosphorus pentoxide releases 68 kilojoules of heat. Under normal circumstances, it reacts with cold water to form pyrophosphoric acid, and with hot water mainly forms orthophosphoric acid. Different pentavalent phosphorus-containing oxides are formed depending on the amount of water added, such as pyrophosphoric acid, pyrophosphoric acid, and orthophosphoric acid, etc.

    The aim is to be able to produce enough food, feed, fiber and renewable raw materials for a growing world population on the limited land available. This is one goal of the Crop Science Division, which has businesses in crop protection, seeds and nonagricultural applications.


    Crop Protection and Seeds
    Crop protection products should act selectively in the smallest possible amounts and then quickly decompose into neutral substances. Modern insecticides control insect pests while sparing pollinators and other beneficial insects. Herbicides selectively suppress weeds without harming the crop. And many fungicides serve to make plants more resistant to microscopic pathogens. In their search for new active ingredients, our researchers are increasingly guided by nature’s strategies. Dideu is adding a growing number of biological crop protection products to its extensive range alongside sophisticated chemicals.


    Our seeds are adapted to local soil and climatic conditions and give high yields. When breeding new varieties, we also take into account consumer requirements, such as the flavor of vegetables. Whether their work focuses on rice, vegetables, cotton or oilseed rape / canola, our research centers worldwide always have the same goals: to protect harvests from diseases, insect pests and encroaching weeds and to improve plant health, thus increasing yields and improving crop quality. We have expanded our research activities to include two new core crops – wheat and soybeans. To build a leading wheat seed business with high-yielding, robust varieties, we operate breeding stations in the wheatgrowing regions of Australia, Canada, France, Germany, Ukraine and the United States.


    Fight against Tropical & Subtropical Diseases
    Crop Science supports public health and adherence to hygiene standards through its modern range of pest control products. One focus here is on the control of insects that transmit tropical or subtropical diseases such as malaria, dengue fever and Chagas disease.


    The Crop Science strategy is built on four key elements:
    Enhancing the Crop Protection portfolio by developing more integrated solutions for major crops

    Increasing customer centricity along the entire value chain

    Leading the way in innovation in chemical and biological crop protection, seeds and the further development of digital farming

    Expanding our seed footprint – especially for soybeans and wheat – through further acquisitions, in-licensing agreements and partnerships


    Animal Health Subsidiary

Our Advantage product family for flea and tick control has been a market leader for years. When animals fall sick, we can help with a range of treatment options, especially for bacterial infections.

    Farm animals, fish and bees supply foods such as milk, eggs, fish, meat and honey. Their health is therefore of special importance for humans. For this reason our portfolio includes products both for treating sick animals and for preventing disease occurrence. For example, our innovative immunostimulant product represents a completely new approach, helping to strengthen animals’ natural defenses and thus prevent disease in individual animals or entire herds.


    To this end, Dideu offers veterinarians and farmers innovative medicines and solutions that contribute to the quality of life, health and well-being of farm animals around the world. Among the important areas are in the treatment and prevention of parasitic diseases, anti-infectives, pharmacological therapies and farm hygiene. We also have an ongoing quest to discover and develop new and innovative therapies to make the world a better place for animals and humans.


    companion animals are treated with our products each year to protect them from external parasites – as are 25 percent of farm animals.


    Diseases cause pain and suffering in animals, too. We support animal owners in preventing pain or ensuring responsible treatment. We also participate in animal welfare projects worldwide, including one to protect mine detection dogs in Cambodia.


    Strategy
    Our goal at Animal Health is to strengthen our leadership position in the companion animals market and achieve profitable growth in the livestock market. We aim to achieve this by expanding our research and development activities and through selective in-licensing and acquisitions.
