Patent DE-3919098-A1 (DE)
Inventor: THOME ROLAND DR
IPC: C01B39/36
Filed: 1989-06-10
Abstract: 2.1 The synthesis of zeolites without using organic compounds proceeds very slowly under normal conditions, which means that there has hitherto been no purely inorganic large-scale industrial process without organic compounds for the preparation of aluminosilicates having a pentasil structure and with a high silica content. 
<??>2.2 The aim is to develop a process for the preparation of crystalline, zeolitic aluminosilicates having an SiO2/Al2O3 molar ratio of >/= 20 by hydrothermal crystallisation without using organic compounds, which process can be carried out on a large industrial scale and gives a product which is free from crystalline side phases. 
<??>The process is characterised in that the following molar ratios exist in the reaction batch:
 SiO2/Al2O3 = 20 - 60
 OH<->/SiO2 = 0.10 - 0.20
 H2O/SiO2 = 20 - 60
 and the hydrothermal crystallisation is carried out in two steps, the first step being carried out in the temperature range of from 245 to 325 DEG C for from 1 to 20 minutes and the second step being carried out in the temperature range of from 120 to 225 DEG C for from 1 to 100 hours. 
<??>2.3 A preferred application of the process relates to the purely inorganic preparation of crystalline, zeolitic aluminosilicates.

Patent DE-3930312-A1 (DE)
Inventor: ECKSTEIN FRITZ PROF DR
IPC: C12Q1/44
Filed: 1989-09-11
Abstract: A method for direct sequencing of nucleic acid chains by denaturation followed by amplification of the regions to be sequenced by repetition of a cycle includes a) a nucleic acid synthesis step in which the nucleic acid to be sequenced is replicated, as a matrix strand in the presence of the four deoxynucleoside triphosphates, by a polymerase, starting from oligonucleotide primers which are complementary to the 3' ends of the antiparallel strands of the nucleic acids to be sequenced; followed by b) a denaturation step. The ends of the resulting nucleic acids are marked during or after amplification. Sequencing of the marked nucleic acids is carried out by incorporating modified nucleotides at positions speicific for a particular base, shortening the amplified nucleic acids to these respective positions and separating the resultant nucleic acid fragments by electrophoresis. The modified nucleotides are incorporated during amplification in four different cycles by using a deoxynucleoside- alpha -thiotriphosphate together with each of the three other unmodified deoxynucleoside triphosphates instead of the four deoxynucleoside triphosphates.
