BLEACHING POWDER ( Chlorinated lime)

 BLEACHING POWDER (Chlorinated lime)



BRAND NAME:- BLEACHING POWDER, BLEACHING AGENT 



BLEACHING powder is  an inorganic compound .Obtained by the action of chlorine on lime;  resulting in a mixture of calcium chloride and calcium hypochlorite. On exposure,it decomposes releasing 30-35% W/W chlorine .



PREPARATION of BLEACHING POWDER :-

The manufacture of bleaching powder is carried out in Bachmann’s plant as follows:-

The entire system is prepared for the manufacturing of bleaching powder, containing a vertical cast-iron tower packed with a hopper at the top, two inlets near the base (one for chlorine and the other for hot air) and an exit for waste gases near the top. This tower is then fitted with shelves that are placed at varying heights with rotating rakes. The shelves are a total of eight in number. Slaked lime is introduced into the hopper. It eventually comes in contact with chlorine moving slowly in the upward direction. The bleaching powder is then collected at the base in the barrel area of the tower. 

Conditions to be looked after during the manufacture: 


•The chlorine used should be dilute in nature. 

•The temperature should be maintained below 40°C.



PROPERTIES OF BLEACHING POWDER:-


Bleaching Powder is a pale yellowish powder that possesses a strong smell of chlorine. 


It performs a reaction with dilute acids to produce chlorine. 

It is soluble in cold water. The lime is left as an insoluble residue on dilution.

On reaction with an excess of a dilute, for instance, dilute sulphuric acid, the chlorine from the bleaching powder gets liberated. 

Thereby, the chlorine that is produced as a result of the action of dilute acid on bleaching powder acts as a bleaching agent. Therefore, chlorine is the bleaching agent in bleaching powder. 



USED:- 

It is used as a disinfectant for drinking water, swimming pools and sanitizer for privies ,etc.


SIDE EFFECTS:- UNKNOWN


DOSE:- UNKNOWN

BOTULINUM TOXIN Uses, Side Effects, and More

 BOTULINUM TOXIN ( A or B ) BRAND NAME:- BOTOX ,DYSPORT  BOTULINUM TOXIN  A and B are highly potent exotoxins produced by Clostridium botulinum that are responsible for ' botulism' ( a type of food poisoning). These neurotoxic proteins cause long- lasting loss of cholinergic transmission by interacting with axonal proteins involved in exocytotic release of Ach. Localized injection of minute quantity of botulinum toxin.  PHARMACODYNAMIC :- Botulinum toxin A inhibits the release of acetylcholine, relieving muscle contraction and spasm associated with many conditions, such as incontinence and dystonia. Cosmetically, botulinum toxin A paralyses muscles in the face to temporarily treat wrinkles. The maximum effects of muscle paralysis occur four to seven days after a dose.When injected at therapeutic doses, botulinum toxin A causes partial chemical denervation of muscle tissue, causing local reduction of muscle activity. Muscle atrophy may result, axonal sprouting may beg...

Clonazepam used, Side effects, Dose, & more

Clonazepam  Brand name:- Lonazepam , Clonapax , Rivotril 0.5, 1.0, 2.0 mg tab. Clonazepam is a benzodiazepine. It works by increasing the action of a chemical messenger (GABA) which suppresses the abnormal and excessive activity of the nerve cells in the brain. Pharmacodynamic:- The pharmacodynamic properties of clonazepam are common among benzodiazepines and include anticonvulsive, sedative, muscle relaxing and anxiolytic effects . Animal data and electroencephalographic investigations in man have shown that clonazepam rapidly suppresses many types of paroxysmal activity including the spike and wave discharge in absence seizures (petit mal), slow spike wave, generalized spike wave, spikes with temporal or other locations, as well as irregular spikes and waves Label . Moreover, the agent can also decrease the frequency, amplitude, duration, and spread of discharge in minor motor seizures Label . Generalized EEG abnormalities are more readily suppressed by clonazepam than are focal ...

CLOMIPHENE CITRATE Uses, Side Effects, and More

 CLOMIPHENE CITRATE BRAND NAME:- CLOMIPHENE, FERTOMED, CLOFERT, CLOME 25,50,100mg tab.  Clomiphene is a selective estrogen receptor modulator (SERM) which treats female infertility. It works by promoting the release of reproductive hormones. This helps stimulate the release of eggs from the ovary (ovulation). PHARMACODYANIMCS:- Clomifene (previously clomiphene) is an orally administered, non steroidal, ovulatory stimulant that acts as a selective estrogen receptor modulator (SERM). Clomifene can lead to multiple ovulation, and hence increase the risk of conceiving twins. In comparison to purified FSH, the rate of ovarian hyperstimulation syndrome is low. There may be an increased risk of ovarian cancer and weight gain. Clomifene is capable of interacting with estrogen-receptor-containing tissues, including the hypothalamus, pituitary, ovary, endometrium, vagina, and cervix. It may compete with estrogen for estrogen-receptor-binding sites and may delay replenishment of intracel...
