Alcoholism prevention

Tetrahydrofurfuryl alcohol is a solvent and coupling agent for a phosphate-type insecticide used to control the gypsy moth. Esters of tetrahydrofurfuryl alcohol are used in preparations employed as insect repeUents. Tetrahydrofurfuryl alcohol is also used as a solvent—carrier for an EPA-approved paper sHmicide formulation. In this appHcation, the exceptional solvent action of tetrahydrofurfuryl alcohol prevents separation of the... 

In suspension polymerization, the monomer gets dispersed in a liquid, such as water. Mechanical agitation keeps the monomer dispersed. Initiators should be soluble in the monomer. Stabilizers, such as talc or polyvinyl alcohol, prevent polymer chains from adhering to each other and keep the monomer dispersed in the liquid medium. The final polymer appears in a granular form. 

Superficial skin infections are treated without antibiotics. Local hygiene and disinfection with alcohol prevents spread of furunculosis. Local application of gentian violet in water (1%) is effective for impetigo. All pus collections must be drained by puncture or incision. Antibiotics are required only when systemic signs of infection are present or in patients with a high risk of complications (e.g. to prevent bacteraemia in a patient with prostheses or intravascular devices).

The use of methyl alcohol prevents, to a large extent, the formation of troublesome emulsions. Less than 0.1 g. of dodecyl bromide dissolves in 100 cc. of 50 per cent methyl alcohol at room temperature. 

This method was introduced by Staab and is suitable for the acylation of primary, secondary and tertiary alcohols. First the carboxylic acid is converted into the imidf lide (42) with carbonyldiimidazole (41), and then the alcohol is added together with a catalytic amount of strong base (alkoxide). The ester is formed at room temperature within a few hours (equation 17). If functional groups in the acid or alcohol prevent the use of base, the imidazolide and the alcohol have to be heated to 70 °C for 1-2 h. 

Lead sub-acetate precipitates gum arabic in aqueous solution. In presence of sugar, addition of alcohol prevents the precipitation of dextrin if the latter is present. 

Solutions containing more than 2 pg of Mg per ml are unstable and soon become turbid as Mg(OH)2 coagulates. Protective colloids, such as poly(vinyl alcohol) prevent the coagulation. Gelatine, gum arable, and starch are also used. 

The supernatant layer of alcohol prevents the reactants dropping directly onto the sodium ethoxide and causing local overheating. 

As atmospheric pressure is an important element in the operation, it will not answer to shut it off by closing the top of the displacer without making some compensation and, therefore, a communication between the upper and lower vessels is established by means of a latent tube arrangement, f. In this manner the apparatus is kept close, and the evaporation of alcohol prevented, while the pressure produced is distributed throughout the apparatus, and rendered uniform. As the runnings are clear, filtration is rarely necessary. The quantity of alcohol thus consumed need not be more than sufficient to exhaust the material and the resulting tincture must therefore be diluted to the proper strength. For perfumes, deodorized alcohol must always be used. 

Chloroform slowly undergoes decomposition when exposed to air and light. Among the products formed are chlorine, hydrochloric acid, and carbonyl chloride, COCI2. The presence of about one per cent of alcohol prevents, to a large extent, the decomposition. Chloroform should be kept in the dark or in a bottle of non-actinic glass. 

To check for complete Dde deprotection, perform absorbance measurements at 301 nm. Collect cleavage mixture after first deprotection step, wash the resin with 1 mL DMF, and combine both solutions (final volume 1.5 mL). Do the same after the last deprotection step. High absorbance values (>10) are expected for the first cleavage step, whereas absorption should not exceed 0.1 for the last. Important Unsaturated hydrocarbons, like the alkene functionality of the Aloe protecting group, are reported to be effected by this cleavage reaction [36]. Therefore, the addition of 200 equiv. allyl alcohol prevents these moieties from reduction.
