Эффективность бурения в значительной мере зависит от условий строительства скважины, а также от качества и свойств бурового раствора. Исследование эффективности применения различных компонентов промывочной жидкости всегда остается актуальным. Авторы провели сравнительный анализ ряда полисахаридных реагентов в составе буровых растворов.

The catalytic cyclopropanation of cis- and trans-1,3-dichlorpropenes with methyl diazoacetate in the presence of a copper catalyst was studied. The products composition and ratio were shown to depend on the spatial structure of 1,3-dichloropropene.

When the O-alkylation of monoallil ether of ethylene glycol by individual cis-and transisomers of 1,3-dihloropropenes obtained in high yields the corresponding unsymmetrical disconnected allilchlorallil esters. Shown that interaction of dichlorcarbenes with unsymmetrical unsymmetrical dialkenil glycol ethers under phase transfer catalysis leads to a sequential formation of the corresponding mono-and bis-gem-dichlorocyclopropyl derivative, here, according to results of kinetic analysis, allyl double bond is approximately 1.5-2 times more active chlorallil bond.

Weed-killing activity of chloroalkenyl ethers and substituted for 1,3-dioxans is studied. It is found that row of the studied compounds possess high growth regulation ability in relation to a sunflower and wheat.

1,3-dichlorpropenesbased butyl and phenylchlorallyl ethers are obtained, the reaction of dichlorcarbenation of these ethers is carried out. The structures of the obtained compounds are identified with the method of chromatographymass spectrometry.

Monoand bis-heme-dichlorocyclopropanes on the basis of symmetric and asymmetrical diolefins are received. Rate constants of their reaction are calculated at significant surplus of chloroform.

The method of competitive reactions studies relative activity of stereoisomerism 1,3 dichlorpropenovs in reactions Oalkylation and dichlorocarbenation. It is established that in reaction Oalkylation of trancesisomery 1,3 dichlorpropena approximately in 5 times the tsis isomery, and in reaction dichlorocarbenation is more active, on the contrary, in 2 times is less active.

Monoand bis(heme-dichlorocyclopropanes) on the basis of symmetric and asymmetrical diolefins are received and speed constants of their formation reaction ave designed at significant excess of chloroform.

Dichlorocarbenation of 4-vinylcyclohexene in conditions interphase сatalysis proceeds mainly on endocyclic double connection and results to bicyclic product through intermediate formation unsaturated hem-dichlorocyclopropanes.

Relative activity endo-and exocyclic double connections of 4 vinylcyclohexene in reaction with dichlorocarbene is investigated by a method of competitive reactions. It is established, that endocyclic double connection in 8 times is more active, than exocyclic.
