Contracts are crucial written or verbal agreements your business has with third parties, such as clients, staff members, business partners, or suppliers. The main goal of contract management is to simplify the process of working with agreements and reduce potential hazards like missing documents or missed deadlines. By putting the strategies listed below in place, you may be able to handle your contracts and contractual obligations more effectively. Also, we recommend using Salesforce CLM software if you want an effective contact management. 1. Pick the most qualified contract manager A strong contract manager will be knowledgeable about particular facets of contract regulations…

Preparation of Mercury Fulminate Mercury Fulminate: 5 g of metallic mercury is added to 35 ml of concentrated nitric acid (d=1.42 g/ml) in a 100-ml Erlenmeyer flask, and the mixture is allowed to stand without shaking until the mercury has gone into solution. The acid liquid is then poured into 50 ml of 90% alcohol in a 500-ml beaker in the hood. Mercury Fulminate: The temperature of the mixture rises, a vigorous reaction commences, white fumes come off, and crystals of merury(II) fulminate soon begin to precipitate. Red fumes appear and the precipitation of the fulminate becomes more rapid, then white…
Preparation of Calcium Sulfide Calcium Sulfide: Unless the charcoal is already very finely powdered, it should be ground thoroughly in a large porcelain mortar. 48 g of charcoal are mixed with 145 g of gypsum (CaSO4 • 1/2H2O; plaster of Paris) and placed in the clay crucible. Calcium Sulfide: The crucible is heat in a gas furnace to between a bright red and a yellow heat for 1.5 hours. At the end of the reaction, the crucible is removed from the furnace and when cold, the contents of the crucible are inspected and there should be no unburned charcoal left. A small sample should dissolve with…
How to Make Chloroform How to Make Chloroform: 200 g of fresh bleaching powder are ground up to a thin paste with 800 ml of water. The mixture is transferred to a large flask fitted with a distillation condenser and receiving flask. 40 g of acetone or ethanol are then added and the reaction mixture is cautiously heated until the reaction sets in. How to Make Chloroform: The chloroform is removed by distillation and the distillate is washed with dilute solution of sodium hydroxide, dried over calcium chloride, and then redistilled. Chloroform is a heavy colorless liquid with a sweet…
Preparation of Phosphorus Pentachloride The direct reaction of phosphorus trichloride and chlorine under controlled conditions provides a simple method for preparing a high grade and yield of phosphorus pentachloride. A glass apparatus for the synthesis of Phosphorus Pentachloride is shown below. A is a tank of chlorine, however a chlorine prepared by reaction of potassium dichromate and hydrochloric acid also could be used. B, a safety bottle; C, a bubbling bottle to observe rate of flow of chlorine gas, bottle C also serves for drying Cl2; and D, a 2 lite reaction flask – neckless jar fitted with a three-hole stopper.…
Preparation of bromobenzene Bromobenzene: To the round bottom flask fitted with stirrer, reflux condenser and dropping funnel 50 g of dry benzene and 0.5 g of pyridine (to act as a halogen carrier) are placed. From the dropping funnel 120 g (40 ml) of bromine are slowly added. A vigorous reaction begins at 25-30° C with evolution of hydrogen bromide. When the reaction has moderated, the temperature is slowly raised to 65-70° C and maintained at this point until the evolution of hydrogen bromide has almost ceased. After cooling, the contents of the flask are well washed with dilute solution…
Preparation of Lead(II) nitrate Lead(II) nitrate: Lead nitrate is one of the most readily prepared salts of lead. Lead oxide (litharge), lead carbonate or metallic lead is treated with an excess amount of concentrated nitric acid. When the reaction mixture cools the crystals of lead(II) nitrate crystallizes. Lead(II) nitrate is separated by filtration and purified by recrystallization. If an insufficient amount of nitric acid is used, the basic salt of lead nitrate (Pb(OH)NO3) forms, which separates as a fine granular or flaky precipitate when the solution cooled. Synthetic inorganic chemistry, by A. A. Blanchard, 277-278, 1936 Into an apparatus as illustrated…
Preparation of p-benzoquinone benzoquinone – quinone Quinone usually is prepared by the oxidation of aniline in acid solution with sodium dichromate. On a laboratory scale the yield is only about 35% and the process is somewhat lengthy. A rapid method of preparing pure Qunione consists in oxidizing hydroquinone with manganese dioxide in an acid medium and removing the product from the reaction mixture by steam distillation. Oxidation of hydroquinone is a more satisfactory regarding starting material than aniline for the laboratory production of Q. Furthermore, the yield is much better. The reaction is carried out in a 2-liter flask having a…
Preparation of Cyclohexanol Cyclohexanol: For the preparation of nickel catalyst, small pieces of pumice stone of a convenient size are soaked in a concentrated solution of nickel nitrate in distilled water, and heated in a basin over a free flame until the nitrate has been converted into the nickel oxide. Cyclohexanol: Alternatively, the pumice is impregnated with a paste of its own weight of nickel oxide and distilled water, and dried on a water bath. The nickel oxide is reduced by heating in a current of pure, thoroughly dried hydrogen in a combustion tube. A combustion tube 1 metre long is…
Preparation of Aluminum Sulfide Aluminum sulfide can be prepared directly from aluminum and sulfur, but when the finely divided substances are mixed and the mixture is heated, either the sulfur entirely distils off without any reaction taking place, or if a reaction starts it is too violent to control. Lead sulfide could be as a source of the sulfide ion because this substance is not volatile and cannot escape before it reacts, furthermore, the reaction is not too violent. 359 g of powdered lead sulfide and 27 g of granulated aluminum are mixed together. The mixture is transferred in the clay…
