Physical data

    Appearance: Colourless oily liquid
    Melting point: -2 C
    Boiling point: 327 C
    Specific gravity: 1.84
    Vapour pressure: <0.3 mm Hg at 20 C (vapour density 3.4)
    Flash point:
    Explosion limits:
    Autoignition temperature:
    Water solubility: miscible in all proportions

Stability

    Stable, but reacts with moisture very exothermically, which may enhance its ability to act as an oxidizing agent. Substances to be avoided include water, most common metals, organic materials, strong reducing agents, combustible materials, bases, oxidising agents. Reacts violently with water - when diluting concentrated acid, carefully and slowly add acid to water, not the reverse. Reaction with many metals is rapid or violent, and generates hydrogen (flammable, explosion hazard).

Toxicology

Extremely corrosive, causes serious burns. Highly toxic. Harmful by inhalation, ingestion and through skin contact. Ingestion may be fatal. Skin contact can lead to extensive and severe burns. Chronic exposure may result in lung damage and possibly cancer.

Organic Fertilizers, Fungicides & Nutrients

Image
Organic fertiliser is obtained from various chemicals. It contains range of nutrients at different ratio, making it effective for plants. These are easily absorbed in plant systems. Organic Fertiliser are available as solid spray dried powder or liquid solution. This powder if fully soluble in water and can be dissolved in water to prepare formulation of required concentration HUMIC ACID: Application of humic acids has several benefits and agriculturists all over the world are accepting humic acids as an integral part of their fertilizer program. Biochemical active and plant responsive humic substance are naturally occurring humic acids. They can be applied directly to the plant foliage in liquid form or to the soil in the form of granules alone or as fertilizer mix. Benefits of Proper Application of Humic Acid increase soil fertility, Increase humus contents, Effectively chelates meta

Biofertilizers Some Facts

1. What is biofertilizer? Biofertilizers are ready to use live formulates of such beneficial microorganisms which on application to seed, root or soil mobilize the availability of nutrients by their biological activity in particular, and help build up the micro-flora and in turn the soil health in general. 2. Why should we use biofertilizers? With the introduction of green revolution technologies the modern agriculture is getting more and more dependent upon the steady supply of synthetic inputs (mainly fertilizers), which are products of fossil fuel (coal+ petroleum). Adverse effects are being noticed due to the excessive and imbalanced use of these synthetic inputs. This situation has lead to identifying harmless inputs like biofertilizers. Use of such natural products like biofertilizers in crop cultivation will help in safeguarding the soil health and also the quality of crop products. 3. What are the benefits from using biofertilizers? Increase crop yield by 20-30%.

CarBon Di-Oxide

Carbon dioxide gas is colourless and odourless gas or extremely cold liquid under pressure or refrigeration. It will not burn. Carbon dioxide is a COMPRESSED GAS. It Can displace oxygen in air, it may accumulate in low areas and is a confined space hazard. Carbon dioxide is a very mild central nervous system depressant. Very high concentrations may cause headache, nausea, dizziness, sweating, restlessness and disorientation. Liquefied gas may cause frostbite. Where do you find carbon dioxide gas? CO 2 gas is used for the carbonation of beverages; for pH control; as a chemical intermediate; in chemical processing; as a food preservative; as an inert "blanket"; and in enhanced oil and gas recovery. Liquid CO 2 is used as a refrigerant; for low temperature testing of aviation, missile and electronic components; as a fire-extinguishing agent; for stimulation of oil and gas wells and for controlling temperature in chemical reactions. CO 2 gas is a by-product of carbonaceous
