Halides Sentence Examples

It is a most important synthetic reagent; with sodium or sodium ethylate it forms sodio-malonic ester, which reacts readily with alkyl halides, forming alkyl malonic esters, which are again capable of forming sodium derivatives, that by further treatment with alkyl halides yield the di-alkyl malonic esters.

The N-derivatives are prepared by the action of alkyl halides and acid chlorides on potassium pyrrol.

The organic derivatives of silicon resemble the corresponding carbon compounds except in so far that the silicon atom is not capable of combining with itself to form a complex chain in the same manner as the carbon atom, the limit at present being a chain of three silicon atoms. Many of the earlier-known silicon alkyl compounds were isolated by Friedel and Crafts and by Ladenburg, the method adopted consisting in the interaction of the zinc alkyl compounds with silicon halides or esters of silicic acids.

The atomic weight of silicon has been determined usually by analysis of the halide compounds or by conversion of the halides into silica.

The mixed tertiary amines are produced by the action of alkyl halides on the primary amines.

Ammonia gas has the power of combining with many substances, particularly with metallic halides; thus with calcium chloride it forms the compound CaCl 2.8NH 3, and consequently calcium chloride cannot be used for drying the gas.

A characteristic property of the alkaline fluorides is their power of combining with a molecule of hydrofluoric acid and with the fluorides of the more electro-negative elements to form double fluorides, a behaviour not shown by other metallic halides.

Grignard (Comptes rendus, 1900 et seq.) observed that magnesium and alkyl or aryl halides combined together in presence of anhydrous ether at ordinary R temperatures (with the appearance of brisk boiling) to form compounds of the type RMgX(R = an alkyl or aryl group and X = halogen).

With unsaturated alkyl halides the products are only slightly soluble in ether, and two molecules of the alkyl compound are brought into the reaction.

They may also be prepared by heating the alkyl halides with silver oxide.

They behave as unsaturated compounds, combining with oxygen to form peroxides and with the halogens to form triarylmethane halides.

It is a tertiary base, and combines readily with the alkyl halides to form pyridinium salts.

The tertiary phosphines are characterized by their readiness to pass into derivatives containing pentavalent phosphorus, and consequently they form addition compounds with sulphur, carbon bisulphide, chlorine, bromine, the halogen acids and the alkyl halides with great readiness.

It combines readily with the alkyl halides.

The mercaptans may be prepared by the action of the alkyl halides on an alcoholic solution of potassium hydrosulphide; by the reduction of the sulpho-chlorides, e.g.

Complexes of carbon, their synthesis and structures, are discussed including the halides, oxides and carbides.

The stress bar has been cut away as i had metal halides over the tank and they would have melted it.

You can use colored metal halides in these floodlights, call or e-mail us for details.

Look at all of the values for the silver halides.

Why don't the other hydrogen halides behave in the same way?

Just one Merlin engine would pump out several pounds of lead halides on a sortie to Berlin; almost chemical warfare!

There are also interactive links for energy tables needed for all the alkali metal halides.

These include the nitrides, halides, oxides and hydrides.
